mature in Christ — Blog

17 Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do, in the futility of their minds. 18 They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart. 19 They have become callous and have given themselves up to sensuality, greedy to practice every kind of impurity. 20 But that is not the way you learned Christ!— 21 assuming that you have heard about him and were taught in him, as the truth is in Jesus, 22 to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, 23 and to be renewed in the spirit of your minds, 24 and to put on the new self, created after the likeness of God in true righteousness and holiness. – Ephesians 4:17-24 ESV

Paul has made perfectly clear his expectation of the Ephesian believers. They were to “grow up in every way into him who is the head, into Christ” (Ephesians 4:15 ESV). He was demanding that they display the kind of maturity that accompanies faith in Christ. Through the efforts of faithful apostles, prophets, evangelists, shepherds and teachers, they had been equipped to do the work of the ministry (Ephesians 4:11). And they were to busy about “building up the body of Christ” (Ephesians 4:12 ESV), so that each of them might increase in maturity and no longer respond like gullible and easily manipulated children.

And this led Paul to call the Ephesians to put their pasts behind them. They were no longer to live according to their former standards or reflect their old way of life.

Live no longer as the Gentiles do, for they are hopelessly confused. – Ephesians 4:17 NLT

Here, Paul is referring to those who outside the family of God. His use of the term, “Gentiles” is meant to include all those who have failed to place their faith in Christ. Many within the congregation to which Paul was writing were actually Gentiles or non-Jews. But his point was that even those who were considered Gentiles before coming to faith in Christ, were now members of God’s family. They had been adopted as His sons and daughters and were His beloved children. And, as such, they were expected to live out their new identity as rightful heirs of the kingdom of God.

Paul was declaring that their new relationship with God should reflect a new allegiance that manifested itself in a new form of behavior. And the apostle Peter promoted this radical change in lifestyle as well.

So you must live as God’s obedient children. Don’t slip back into your old ways of living to satisfy your own desires. You didn’t know any better then. But now you must be holy in everything you do, just as God who chose you is holy. – 1 Peter 1:14-15 NLT

Notice the words that Paul uses to describe their former state as non-believers: Futile, darkened, alienated, ignorant, hardhearted, callous, sensual, greedy, and impure. Not exactly a flattering list of characteristics. But Paul isn’t emphasizing visible manifestations of outward behavior. He is stressing a way of life that begins in the heart and flows out in tangible expressions of life change.

There is a link between verse 1 and verse 17 of chapter four. In both verses, Paul uses the Greek word peripateō, which can mean “to walk” or “to live one’s life.” In verse one, Paul urged the Ephesians to “walk (peripateō) in a manner worthy of the calling to which you have been called.” Then, in verse 17, he states, “you must no longer walk (peripateō) as the Gentiles do, in the futility of their minds.”

Essentially, Paul was telling the Ephesians that it was impossible to do both at the same time. You can’t simultaneously lead a life worthy of your calling and live hopelessly confused like the Gentiles do. It had to be one way or the other, and it was time for the Ephesians to make up their mind which way would characterize their lives. There was a real temptation for those Gentiles within the church in Ephesus to fall back into their old way of living. They were constantly surrounded by friends and family members outside the body of Christ whose behavior reflected their former lifestyle. And it was very tempting to look back on their pre-conversion life and view it through rose-colored glasses. But Paul wants them to see their past as what it was: Dark and far from hopeful. He reminds them that their lost neighbors are hopeless and helpless, trapped in an endless cycle of sin with no way of escape.

Their minds are full of darkness; they wander far from the life God gives because they have closed their minds and hardened their hearts against him. They have no sense of shame. They live for lustful pleasure and eagerly practice every kind of impurity. – Ephesians 4:18-19 NLT

But the Ephesians knew better. Their eyes had been opened to the truth and their hardened hearts had been softened by the regenerating work of the Spirit of God.

…he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit, whom he poured out on us richly through Jesus Christ our Savior… – Titus 3:5-6 NLT

They had been transformed from sinners into saints, from enemies of God into His beloved sons and daughters. And they were no longer trapped in darkness and blinded to reality of their own sin and their desperate need for a Savior.

…he has rescued us from the kingdom of darkness and transferred us into the Kingdom of his dear Son, who purchased our freedom and forgave our sins. – Colossians 1:13-14 NLT

So, in keeping with their new status as God’s children, Paul commands them to “throw off your old sinful nature and your former way of life, which is corrupted by lust and deception” (Ephesians 4:22 NLT). They were to treat their former way of life like an old filthy garment and discard it. But removal of their old nature was not enough. It needed to be replaced with something better.

Put on your new nature, created to be like God—truly righteous and holy. – Ephesians 4:24 NLT

And Paul expands on this spiritual wardrobe change in his letter to the church in Colossae.

So put to death the sinful, earthly things lurking within you. Have nothing to do with sexual immorality, impurity, lust, and evil desires. Don’t be greedy, for a greedy person is an idolater, worshiping the things of this world. Because of these sins, the anger of God is coming. You used to do these things when your life was still part of this world. But now is the time to get rid of anger, rage, malicious behavior, slander, and dirty language.Don’t lie to each other, for you have stripped off your old sinful nature and all its wicked deeds. Put on your new nature, and be renewed as you learn to know your Creator and become like him. – Colossians 3:5-10 NLT

Out with the old, in with the new. That’s the gist of Paul is saying. The new lifestyle that God had made possible through the death, burial, and resurrection of His Son was to be far from business-as-usual. By redeeming the Ephesians believers, God had spared them from the judgment to come. Their sins had been forgiven and their eternal life had been secured for them by Christ. And the indwelling presence of the Spirit of God was meant to act as a guarantee that God’s future promises would be fulfilled just as He had said. That’s why Paul encourages the Ephesians to “let the Spirit renew your thoughts and attitudes” (Ephesians 4:23 NLT). Their ongoing transformation would be the work of the Spirit of God, not just the result of their own human effort.

When Paul speaks of putting off and putting on, he is not suggesting that the individual believer has control over their own sanctification. He is not laying the heavy weight of spiritual maturity on the shoulders of the saints. But he is suggesting that they have a role to play. They must willingly submit to the Spirit’s leading as He lovingly guides their steps. That is why Paul used that Greek word, peripateō when addressing the believer’s relationship with the Spirit of God.

But I say, walk (peripateō) by the Spirit, and you will not gratify the desires of the flesh. – Galatians 5:16 ESV

In other words, the believer is to live their life in accordance with the Spirit’s leading. And Paul goes on to explain how every Christian has a daily to choice to either live according to the desires of their old nature or in obedience to the Spirit of God.

The sinful nature wants to do evil, which is just the opposite of what the Spirit wants. And the Spirit gives us desires that are the opposite of what the sinful nature desires. These two forces are constantly fighting each other… – Galatians 5:17 NLT

By submitting to the Spirit, the believer experiences the ongoing renovation of their thoughts and attitudes. They see things differently. They think about things in a whole new way. Their perspective changes. Their outlook on life takes on a whole new light because they no longer live shrouded in a veil of darkness. They are new creations and they should act like. They have new natures and their lives should reflect that reality. They are sons and daughters of God and their lives should bring glory to their heavenly Father.
