In this episode, I want to walk through seven principles of renewing our mind. I think it's worth asking the question, what do I need to do to be conformed to this world? Answer, nothing. You just live in the world. When you are immersed in the world, you are allowing yourself to be influenced by it. This whole business of renewing your mind includes recognizing that I focus on God as the greatest supplier of those longings of my heart. True satisfaction. If you're going to renew your mind, you've got to proactively throughout the day, engage your mind in the truth that transforms it.

And I would want anyone listening to say, number one, born again, transformed by grace, saved by faith, gives you the capacity to have a renewed mind and a renewed heart and a renewed life. Read the Bible, meditate together, rehearse the truth, renounce the lies. watch God change your life. Thanks for listening. This episode is brought to you by the Masters University.

That's where I work with you, Harry. Welcome. Yeah, thank you, John. That's how we know each other. Hey, so we're in a series on really pursuing holiness. We looked at the reality that seeing God is the primary motivation, blessed or the pure in heart, for they shall see God. It means that there's going to be a real intimacy, a real fellowship with God. We looked then, secondly, a couple episodes ago,

at this reality of making no provision for the flesh to cut off the things in our life that constantly, Hebrew says, trip us up. They cause us to stumble. But with that said, you know, when I was a boy, when we lived in Chicago, my dad would employ home alone style protection systems in our house in Chicago like he was afraid of where we lived so I'd wake up and I would see my dad putting little Legos honestly on the windowsill said to think that if a burglar broke into our basement they would step on a Lego and through their shoe they would scream alerting and awaking my dad two stories up and we laugh

because it's obviously an insufficient system to ward off burglars. And in that same way, knowing sin is bad is not enough. It's not enough to transform our affections, our yearnings, our longings, our desires. We need to have our minds renewed, and that's so important as we see throughout the scripture. Yeah, no, 100% true. You don't have the willpower or the resolve sufficient to motivate and move you to success in fighting the flesh and the enemy and the world. Yeah, we need that.

And I want to look to a familiar passage of scripture, at least initially, Romans 121 and 2 says, therefore I urge you, brethren, by the mercies of God, to present your bodies as a living and holy sacrifice acceptable to God, which is your spiritual service of worship, he just saying in light of everything God has done for us in the gospel that our entire life is to be presented on the altar of sacrifice. And then he says in 12, do not be conformed to this world, but be transformed by the renewing of your mind. And he says, so that you may prove what the will of God is. Meaning here, God's will for our life doesn't need to be found. It needs to be proven. And it's by not

being conformed to this world, but be transformed by the renewing of your mind. I like what R.C. Sprole says in the book, pleasing God. He says, the world is a seducer. It seeks to attract our attention and our devotion. It remains close at hand, visible and enticing. It eclipses our view of heaven. And what is seen vies for our attention. It entices our eyes. It entices our eyes. preventing us from watching for a better country whose builder and maker is God, it pleases us much of the time anyway, and alas, we often find our lives trying to please it. He says, there is where the conflict ensues for pleasing the world seldom overlaps with pleasing God. But this is God's will for our life, and that is that our mind is to be renewed.

And I think sometimes here, I want you to speak to this, because I think sometimes we come to the Christian life, and many people have this idea, that it's simply the subtraction of bad behaviors, with the addition of good behaviors, like, don't do these things anymore. We've got to start doing these things now. But it's more than that fundamentally. It's about the transformation of our desires, our affections, our attention, and our allegiance. Speak to that. Yeah, well, I like that a lot.

And a Puritan pastor by the name of Thomas Chalmers has written a book, preached a sermon called The Expulsive Power of a Greater Affection, expulsive meaning the removal the the jettison of desires that are illicit affections because what dominates your heart is a legitimate affection a greater affection so if i love my wife with passion and vigor it diminishes any interest in an alternative affection if you have an affection for god it has the power to expel these lesser affections these illicit ones, these insufficient ones. So this whole business of renewing your mind includes recognizing that I focus on God as the greatest supplier of those longings of my heart. True satisfaction. And I focus on that. And I establish a pursuit of that. And it removes both opportunity and interest in lesser affections. So it is a positive focus on God. the things of God, the life of God, the word of God, the satisfaction that comes from God.

You know, man does not live when Jesus was tempted. They turn the stones into bread, satisfy, gratify. And he said, listen, man does not live by bread alone, but by every word which proceeds out of the mouth of God. There is a kind of soul food through the word of God that satisfies the person of God. so that the desire for the lesser things, the provisions are eliminated and... Well, it's just not interested. I just had a good meal.

It's Thanksgiving. We just had it. You know, I eat a lot. Somebody brings out a dessert. I don't have any room. I'm not hungry. It's not because it's not interesting. I just don't desire it.

Yeah, and all of these things, and we're going to jump into this, have to do with our mind. I like what John Stott says. He says, the battle for the Christian life is the battle for the Christian mind. This is not only something

that an English theologian, claims. It's really the testament and anthem of scripture. As your mind goes, as my mind goes, so goes the entirety of our Christian life. Proverbs 237, as a man thinks within himself, so he is. Ephesians 423, be renewed in the spirit of your mind. Mark 12, love the Lord your God with all your heart, soul, mind and strength. First Peter 113, prepare your minds for action. And then here in Romans 12, too, your mind is to be renewed. So how does this happen? Well, in this episode, I want to walk through seven principles of renewing our mind, not exhaustive this list, but, and there's some overlap here, and we've already touched on a couple of them, but seven principles for

how our minds are to be transformed, and the first of which is to fill our mind with God's word. A simple principle would be what you put in shapes what comes out of your life, and saturation precedes transformation. You are a derivative of what you saturate your mind with. So how does the Holy Spirit work? Well, the Spirit of God takes the Word of God and a child of God to transform them into the image of the Son of God. So if you want your mind to be renewed, you have to first and fundamentally have your mind rooted and planted in the truth of Scripture. Yeah, and it parallels what Proverbs 7 begins with by saying the thing that keeps you from the adulterous and the strange woman, the temptation and gratification in the flesh.

what keeps you all involves the truth of God's word you store it you get Solomon says to his son hey keep my words within you treasure them in your heart yeah apply them treat them as the apple of your eye rehearse them memorize them develop a relationship with them and they will keep you that's the words of God the wisdom of God the instruction of God keeps you from immorality, fleshly thoughts, any violation of the word of God by the desires of the flesh. Hey folks, I want to take a moment and tell you about one of our ministry partners accountable to you. Accountable to you is an accountability software that helps protect and ensure your personal purity and integrity. I've been using this personally for over a year and the way it works is that

whatever you look at is sent to the accountability partners that you have in your life. my wife would be one of those. I have other friends that are a part of that. And the guys on my church staff are also joining me in this endeavor because one of the paths to purity is eliminating any access to anonymity in your life, meaning that if you can look at things on your iPad, your phone, your computer, and say no one will ever know about this, it's going to be really hard to battle for holiness in a world that is so littered with impurity. I would highly encourage you to check out Accountable to you. You can go to their website, accountable to you.com, dial in and use dial in our code to receive 25% off your first year of use.

There's nothing more important than protecting your personal purity as you seek to honor the Lord. And with it, there's a precious promise that we've looked at before. Blessed of the pure and heart, for they shall see God. And accountability is one of the ways that you can ensure that you are protecting your personal purity and seeking to honor the Lord Jesus Christ. You know, kind of at the foundational level, you become like that, which you behold. So the Word of God, Psalm 19, to your point, provides warnings. Moreover, by them your servants is warned, but also promises rewards and promises, you know, that incentivize us, right?

And it transforms our affections. Like in 2nd, Corinthians 317, I always thought this was interesting, Harry, where it says, where the Spirit of the Lord is, there is liberty. Meaning, like, the Christian life is freedom. But then you go, well, how is the Christian life liberty and freedom? Wherever the Spirit of the Lord is, there is liberty when it feels like there is a bunch of rules and regulations. and things I can and cannot do. But then we have to read the next verse. But we all with unveiled face, beholding as an ameer, the glory of the Lord,

are being transformed into the same image from glory to glory, meaning that the Christian life only feels like liberty to the person whose greatest desires to become like the one they behold in the Word of God. And you'll never know who God is unless you are saturating and renewing your mind in the truth of Scripture. So that would be the first one. I think the truth is liberating from a, dominating incarceration of the flesh. You're under the flesh is dominating control unless you're

liberated by the spirit of God through the word of God. True liberty. I can choose. I have the freedom to say no. I have the freedom to say yes. So this idea of freedom is a liberating reality for a Christian dominated by the words of God. I was thinking you mentioned Johnny Psalm 19. I like verse 7, which says, the law of the Lord is perfect. It restores. It refreshes. It renews the soul. Shabbat.

Yeah. The word of God is both the cleansing agent and the transformational means whereby we're renewed, the way we think, the way we, the affections of the heart. Yeah, so important. And that leads us really to secondly here, how to renew our mind. You have to take every thought captive. I wrote in my notes to take. the Philippians 4-8 tests. We know this first potentially, where Paul says,

finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence, if anything worthy of praise dwell on these things, meaning that we don't let any thought in our life run unchecked. We can ask those questions. Is it true? Is it honorable? And we talked about this a little bit beforehand to replace any of the lies that the world flings at us, the the world, the flesh of the devil, and to replace those lies with truth. And here is where, Harry, this idea of renewing your mind isn't just kind of like in a biblical exaggeration. It's an actual scientific reality that our minds need to be transformed. Yeah, I was interesting enough

reading recently, very recently, about the fact that when you rehearse certain ideas or certain thoughts, words, when you rehearse them out loud, you live. literally renew or rewire the neural pathways, the physiological neural pathways in your brain. So let's suppose the habit of my heart is to think a particular thing, I'm no good, I'll never do any good, just these thoughts that are so intrusive or dominating, or hey, nobody will know, I can do this and nobody will know, which is a lie, but it's a lie that I tend to believe and act out on neuroplasticity, which is a scientific thing that I'm becoming more aware of, recognizes the fact that when you rehearse truth after identifying the lie and

renouncing verbally that lie, like it is a lie that no one will know. First of all, Proverbs 521, the eyes of the Lord, behold, the evil and the good. The Lord knows. It's not true that no one knows. That's a lie. I identify it as a lie. I verbally reject it. And then I rehearse the truth out loud. This is neuroplasticity. It's both biblical and it is scientific that I say out loud. No, God knows. He knows because he holds the evil in the good. What I do in secret, God knows. To him, darkness is light. So rehearsing the truth and saying it out loud, and this is the thing I didn't really realize, is the verbalizing it out loud, when my ears hear it, I'm preaching truth to myself from the word of God that is rewiring my thinking patterns.

And the more I repeat that, the more grooved it is. It's literally solidified. Yeah, in your head, your brain, and it's the habit of your heart. And therefore, when you're not thinking, you're thinking, you're defaulting to truth rather than lies. Yeah, so important. I think sometimes we talk about the renewing of our mind and we think, you know, well, that's just something the Bible says. but from a scientific level, neuroplasticity is the rewiring of your brain. So third here is not only to saturate your lives with the Word of God,

not only to take every thought captive, but three, set your mind on things above. Just bottom line, you can't starve your flesh if you keep feeding it. Scripture says in Colossians 3, 2, set your mind on things above, comma, not on earthly things, which means that the scripture is telling us to deliberately and intentionally set our minds on God, The hope of heaven, 1st John 33 says whoever has this hope fixed on him purifies himself even as he is pure, meaning that as we dwell on the person and work of Jesus Christ, where he reigns in heaven right now,

Jesus says, don't let your heart be troubled. Think about heaven. That becomes a purifying agent in our life when we are dwelling upon the reality that this world is not our home. So many of the temptations in this world are because we want to be a part of it. We think this world lasts forever. But Paul says in Colossians, no, set your mind. Not here, but in heaven. Anything to add there? Yeah, I think you mentioned the key thought is what you focus on, and it's also what you choose not to focus on, removing and ignoring. John Owen in his book, famous book, on temptation and the mortification of sin,

talks about the habitual weakening of sin by denying it what it desires. So the things that you said, fuel it, which can be social media, could be friends, could be things we do by virtue. of our association, prompters, triggers. I think social media is just full of triggers and fuel for the flesh.

And gateway drugs to... Yeah, it's just like if you want to succeed on taming your thoughts and controlling your mind, you have to be careful what you expose your mind to. And it's not weakness.

It's wisdom. Yeah. Well, it's just you think about it. You can read your Bible for 15 hours a day and then go roll around in the mud, of the world for 16 hours, you're going to come out polluted. Yeah. The average person spends seven hours a day on social media,

or looking at their phone or looking at a screen. And that really leads us to number four, Harry, which is guard the gates of your mind. I think it's worth asking the question, what do I need to do to be conformed to this world? Answer, nothing. You just live in the world. When you are immersed in the world,

you are allowing yourself to be influenced by it. And that's why Proverbs 423, I remember my dad teaching me this when I was young, of the young, watch over your heart with all diligence for from it flow the springs of life because whatever we consume becomes what we contemplate and whatever we contemplate shapes our character. And so with that, we really need the guard, the gates of our mind. You talked about eliminating some of those things that may be morally neutral and of themselves, but there are a lot of morally neutral things in life that are not explicitly sinful that rob or focus and attention

from dwelling on the things of God. Yeah, no, and that's just, I said it earlier, it's just being wise. If I want to be physically fit and I want to lose weight, it's not immoral to go by the buffet. But if I go to the buffet, I am drawn to the buffet. You're speaking from personal experience. I love the word buffet over Buffett, my body.

But the practical point being, If you want to be successful, it's wise to avoid the prompters of temptation. It's just wise. You guard the gates of your mind, i.e. by what I allow in it, but also where I frequent go where I am challenged to be exposed to something. And I'm not prudish in the sense that I'm afraid. I'm just aware of the fact that I'd rather not be tempted. to have to fight the battle of temptation that's the first you know like how do people ask how do i fight temptation you don't you know well as much as possible you run as fast and as far away from it as possible make no provision yeah make no provision our goal isn't to be in the battle

you know we're in a war but we don't pick we don't pick fights with the flesh five would be to meditate on what is excellent in regards to renewing our mind we've done an episode on this before harry but purity in purity out there's overlap here but the there is a distinction between studying scripture, which is important, reading scripture, which is very important. And then that is different than meditating on scripture and disciplining and training yourself to think God's thoughts after him so that your default thoughts going along with what you said about neuroplasticity are towards godliness. Maybe just touch on that briefly. I know we've talked about it before, but just the importance of meditation as it relates to renewal.

Yeah, we have talked about it before, and it is a whole consideration in and of itself. But the fundamental idea is that you are feeding on the Word of God, and you are ruminating on the Word of God. So you're taking it in, here's the big idea, and you're chewing on it. Throughout the day. Throughout the day. It's a day-long process. Your mind's going somewhere. Yeah, and it's not passive.

It is active and proactive, directing my thoughts to the things of God, the truth of God, which renews my mind and transforms my heart. That's why I'm like a tree planted by streams of water. That's why my leaf doesn't wither. That's why I bear fruit in my in season, because my delight is in the law of the Lord. And the law of the Lord, I ruminate, I meditate day and night throughout the day. And this is a practical action step. If you're going to renew your mind, you've got a proactive. throughout the day engage your mind in the truth that transforms it you chew on it you cough

it up if you will and you think about it you don't have to spend gobs of time but you need to spend multiple installments of time in order to establish a groove in your head and the nourishment for your heart so good uh six here would be worship prayer the people of god i kind of coupled those together but I think communion with God and his people is big one for the renewal. We think about the renewal of our mind as something that's private. And I would say, first of all, you have to have real communion with God because if you don't have intimacy with God, then the temptation to sin or the resistance against sin will feel like

I don't want to violate a principle rather than I don't want to grieve a personal God who loves me and knows me. So there has to be real intimacy. But then also the people of God, you know, we're not lone rangers. And, you know, maybe Harry just reflect on the body of Christ. Like, we think about this idea of we need our minds to be renewed as kind of like a solo project. You know, we serve in the church together, but as it relates to my mind being transformed, that's just something I have to do Monday through Saturday.

But the scripture says that we're to sing the truth, preach the truth to one another. So how does the body of Christ kind of come together on this? Yeah, Christ's likeness is the goal of God for us. Christ likeness should be our goal. Christ likeness is impossible in isolation. The way God has designed sanctification, spiritual progress under Christ's likeness, the way he's designed it includes the gifts of others, the influence of others, the encouragement of others, the accountability to others.

The worship with others, the stimulation of love and good deeds that come through worship when we don't forsake it, there is this communal aspect at the university, we would call it a distinctive, is sanctifying community, sanctifying relationships. My relationship with you and the closeness that we have stimulates me and encourages me. It challenges me and hopefully vice versa. And this idea of brotherhood and community is so critical to success as a Christian. Brothers need brothers. You've heard me say that. Christians need Christians.

Isolation will kill you. You're not strong enough by yourself. Nobody is. So this idea of the body of Christ functioning collectively and together, encouraging, strengthening, supporting, challenging is part of God's plan. so that I become what he saved me to become, which is like his firstborn son. Yeah, you can't live the Christian life alone

without the body of Christ. And seventh here, lastly, in order to renew your mind, my mind, we have to walk in the spirit, not the flesh, meaning that our transformation is not primarily about willpower, but about the spirit's power working in our life. And when we want to become more like Christ, we need to recognize the nature of our dependence on God. Galatians 516 says walk by the spirit and you will not gratify the desires of the flesh.

I think there are a lot of people that I want to just, my mind has to be, you know, change my mind, change my mind. But this is actually something the spirit of God does in our life. That's why in Ephesians 423, it's a passive verb, meaning it's something we're pursuing, but it's actually something that's being done to us through the power of God's spirit. maybe just talk about that nature of spirit dependence that we're not the one changing our minds we have a part to play i think ken hughes calls it holy spirit inspired sweat we are working out our salvation with fear and trembling philippians 212 but the next verse is so important for it is god who works in and through you for his good pleasure so we need god's spirit yeah and i think this

at least for many of us including me sometimes is the overlooking of the necessity Ephesians 518 you know don't be drunk with wine don't be governed by this influence but be filled keep on being filled passive verb present tense keep on filling the spirit of God filling and controlling me so that I won't fulfill the desires of the flesh so that I will fulfill the desires of God and so spirit filling walking in the spirit there's 525 and if Galatians 5 says, since you live by the spirit, walk by the spirit. And the word walk there is different than the first one in 516. It's stay in step with the spirit.

Like he's calling marching cadence orders. You listen to him. The word of God, I call that the black and white, the loud, the obvious. And the prompting of the Holy Spirit, the not so obvious. The word of God rules, but the spirit of God prompts. and his clear cadence, united with his prompting leading, is the direction that you submit to, you obey, and you enjoy both the fruit of the spirit,

the power of the spirit, and the experience of the Holy Spirit. That includes holiness, purity, life, freedom, I mean, the fruit of the Spirit, love, joy, peace, patience, kindness, goodness, faithfulness, meekness, self-control, all of those nine facets are expressions of what happens to me when the spirit of God governs me, when I'm listening, following. And so when you raise the point about walking in the spirit,

honestly, it's last because it's foundational. It could be first because it's essential. Yeah. Yeah, so important. And I think, you know, as you come to a close here, you know, the question has to be asked, who can have a renewed mind? And it's truly only those who have a renewed mind.

renewed heart. What God does in us positionally at the moment of salvation, he provides the power to do that progressively until we meet him face to face. But in order to be walking with the spirit, we have to be indwelt by the spirit of God, which happens when we place our faith in the finished work of Christ. And so I think there are maybe some people that, you know, my mind can't be renewed, I can't be renewed. And you'd have to ask the question, do you have a renewed heart? Because when God changes your hearts. He gives you the capacity to have this renewed mind. And you said it already, Harry, like, you're not incarcerated by the flesh anymore if you're in Christ. You don't have to sin. You've been given a way of escape. You can honor the Lord. Anything else just to add

before we close? Yeah, I just would want to punctuate that. If I'm a slave to sin, if I'm an addict to this pattern, it is possible that I've not been set free by the power of Christ. because one of the things that Jesus Christ said he would do is it would set prisoners free yeah okay he would he would set me free um if the son sets me free jesus said in the gospel of john you preached here recently you're free indeed and so the the importance of being born from above transformed by the spirit i'm a sinner i can't save myself jesus did what i couldn't do paid a debt I couldn't pay, and he's ready to give me a life I can't earn. And by faith, I trust him to forgive me because he paid the price and to transform me

with the righteousness that I can't earn or deserve his. And when that happens, 2 Corinthians chapter 5, I'm a new creation. Old things pass away. All things become new. I'm a new person born again from above. And I would want anyone listening to say, number one, born again, transformed by grace, saved by faith, gives you the capacity to have a renewed mind and a renewed heart and a renewed life. That's the gospel truth.

And that's the hope we have. And these things we talked about, God gives us the power to change. He gives us the means to change his word and the person of his spirit. and with good brothers, and this is the other thing I'd want to punctuate, if you want to tame your thoughts, find a band of brothers or sisters, and say, hey, listen, I need help with this. Will you help me with us? Let's do this together. Read the Bible, meditate together, rehearse the truth, renounce the lies, and watch God change your life. Oh, Harry, thanks so much. Appreciate you, bro.

Thank you, Johnny. Thank you.
