Change Your Mind - Change Your Life
Paul tells the church at Ephesus to stop living the way they used to and let God renew their thinking, because the way a person thinks shapes how they live. The sermon walks through four things that change the mind: being intentional about what you think about, replacing sinful patterns with godly living, learning from Jesus, and surrendering your mind to the Holy Spirit.
The passages
This I say therefore, and testify in the Lord, that you no longer walk as the rest of the Gentiles also walk, in the futility of their mind, being darkened in their understanding, alienated from the life of God because of the ignorance that is in them, because of the hardening of their hearts. They, having become callous, gave themselves up to lust, to work all uncleanness with greediness.
Ephesians 4:17–19
…if indeed you heard him and were taught in him, even as truth is in Jesus: that you put away, as concerning your former way of life, the old man that grows corrupt after the lusts of deceit, and that you be renewed in the spirit of your mind, and put on the new man, who in the likeness of God has been created in righteousness and holiness of truth.
Ephesians 4:21–24
Go deeper
Why can't I just try harder to stop thinking the way I do?
Dennis compared it to being put into a football uniform and handed the ball, when the only one who can actually run with it is the one who belongs on the field. Paul does not tell the Ephesians to grit their teeth; he tells them to let the Spirit renew them. Someone trying to white-knuckle their own thoughts knows exactly how quickly that falls apart.
…and that you be renewed in the spirit of your mind, and put on the new man, who in the likeness of God has been created in righteousness and holiness of truth.
Ephesians 4:23–24
But I say, walk by the Spirit, and you won’t fulfill the lust of the flesh. For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, that you may not do the things that you desire.
Galatians 5:16–17
Then he answered and spoke to me, saying, “This is Yahweh’s word to Zerubbabel, saying, ‘Not by might, nor by power, but by my Spirit,’ says Yahweh of Armies.
Zechariah 4:6
For I know that in me, that is, in my flesh, dwells no good thing. For desire is present with me, but I don’t find it doing that which is good. For the good which I desire, I don’t do; but the evil which I don’t desire, that I practice. But if what I don’t desire, that I do, it is no more I that do it, but sin which dwells in me. I find then the law that, while I desire to do good, evil is present. For I delight in God’s law after the inward person, but I see a different law in my members, warring against the law of my mind, and bringing me into captivity under the law of sin which is in my members. What a wretched man I am! Who will deliver me out of the body of this death? I thank God through Jesus Christ, our Lord! So then with the mind, I myself serve God’s law, but with the flesh, sin’s law.
Romans 7:18–25
Does what I watch and listen to actually change how I think?
Paul describes people whose minds were full of darkness and whose lives followed right behind. Dennis was blunt that something is always molding us, whether we notice it or not. That is why Paul tells the Ephesians to stop living the way the world around them lived.
This I say therefore, and testify in the Lord, that you no longer walk as the rest of the Gentiles also walk, in the futility of their mind, being darkened in their understanding, alienated from the life of God because of the ignorance that is in them, because of the hardening of their hearts. They, having become callous, gave themselves up to lust, to work all uncleanness with greediness.
Ephesians 4:17–19
Keep your heart with all diligence, for out of it is the wellspring of life.
Proverbs 4:23
Finally, brothers, whatever things are true, whatever things are honorable, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report: if there is any virtue and if there is anything worthy of praise, think about these things. Do the things which you learned, received, heard, and saw in me, and the God of peace will be with you.
Philippians 4:8–9
Don’t be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good, well-pleasing, and perfect will of God.
Romans 12:2
How do I tell which thoughts are mine and which are the enemy's?
Paul warns that the serpent deceived Eve in her thinking, and Dennis talked about the devil bombarding the mind with fear, bitterness, and discouragement. The snake did not change Eve's circumstances; he changed her reasoning. That means some thoughts arriving in your head are not neutral.
But I am afraid that somehow, as the serpent deceived Eve in his craftiness, so your minds might be corrupted from the simplicity that is in Christ.
2 Corinthians 11:3
…for the weapons of our warfare are not of the flesh, but mighty before God to the throwing down of strongholds, throwing down imaginations and every high thing that is exalted against the knowledge of God and bringing every thought into captivity to the obedience of Christ,…
2 Corinthians 10:4–5
You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and doesn’t stand in the truth, because there is no truth in him. When he speaks a lie, he speaks on his own; for he is a liar, and the father of lies.
John 8:44
Now the serpent was more subtle than any animal of the field which Yahweh God had made. He said to the woman, “Has God really said, ‘You shall not eat of any tree of the garden’?” The woman said to the serpent, “We may eat fruit from the trees of the garden, but not the fruit of the tree which is in the middle of the garden. God has said, ‘You shall not eat of it. You shall not touch it, lest you die.’” The serpent said to the woman, “You won’t really die, for God knows that in the day you eat it, your eyes will be opened, and you will be like God, knowing good and evil.”
Genesis 3:1–5
If I know what Jesus taught, why does my life not look like it?
Dennis pointed out that you can know Jesus talked about forgiveness and still hold a grudge, or know he taught humility and still chase recognition. Jesus said the wise builder is not the one who heard his teaching but the one who did it. Knowledge sitting in the head has never changed a person on its own.
“Everyone therefore who hears these words of mine and does them, I will liken him to a wise man who built his house on the rock. The rain came down, the floods came, and the winds blew and beat on that house; and it didn’t fall, for it was founded on the rock. Everyone who hears these words of mine and doesn’t do them will be like a foolish man who built his house on the sand. The rain came down, the floods came, and the winds blew and beat on that house; and it fell—and its fall was great.”
Matthew 7:24–27
But be doers of the word, and not only hearers, deluding your own selves. For if anyone is a hearer of the word and not a doer, he is like a man looking at his natural face in a mirror; for he sees himself, and goes away, and immediately forgets what kind of man he was. But he who looks into the perfect law of freedom and continues, not being a hearer who forgets but a doer of the work, this man will be blessed in what he does.
James 1:22–25
Even so faith, if it has no works, is dead in itself.
James 2:17
“Why do you call me, ‘Lord, Lord,’ and don’t do the things which I say? Everyone who comes to me, and hears my words and does them, I will show you who he is like. He is like a man building a house, who dug and went deep and laid a foundation on the rock. When a flood arose, the stream broke against that house, and could not shake it, because it was founded on the rock. But he who hears and doesn’t do, is like a man who built a house on the earth without a foundation, against which the stream broke, and immediately it fell; and the ruin of that house was great.”
Luke 6:46–49
Can I put on a clean outside while my inside stays a mess?
Paul uses clothing language: take off the old nature and put on the new one. Dennis said you can force yourself not to say something while still thinking it. Saul was the obvious case, looking like a king on the outside while the inside corroded. The new self Paul describes is made to reflect God, not just behave cleanly on the surface.
…that you put away, as concerning your former way of life, the old man that grows corrupt after the lusts of deceit, and that you be renewed in the spirit of your mind, and put on the new man, who in the likeness of God has been created in righteousness and holiness of truth.
Ephesians 4:22–24
“Woe to you, scribes and Pharisees, hypocrites! For you clean the outside of the cup and of the platter, but within they are full of extortion and unrighteousness. You blind Pharisee, first clean the inside of the cup and of the platter, that its outside may become clean also. “Woe to you, scribes and Pharisees, hypocrites! For you are like whitened tombs, which outwardly appear beautiful, but inwardly are full of dead men’s bones and of all uncleanness. Even so you also outwardly appear righteous to men, but inwardly you are full of hypocrisy and iniquity.
Matthew 23:25–28
But Yahweh said to Samuel, “Don’t look on his face, or on the height of his stature, because I have rejected him; for I don’t see as man sees. For man looks at the outward appearance, but Yahweh looks at the heart.”
1 Samuel 16:7
Don’t lie to one another, seeing that you have put off the old man with his doings, and have put on the new man, who is being renewed in knowledge after the image of his Creator,…
Colossians 3:9–10
