Conformed Together: The Measurement Is Christ

Conformed Together: The Measurement Is Christ

Scripture does not present conformation as something inherently negative. In fact, one of the clearest statements of God's eternal purpose is that those whom He foreknew He predestined “to be conformed to the image of his Son” (Romans 8:29). At the same time, the same apostle commands believers, “Do not be conformed to this world, but be transformed by the renewal of your mind” (Romans 12:2). These statements are not contradictory, nor does Paul use the language of conformation in exactly the same sense in both passages. The problem, therefore, is not conformation itself. The biblical question is what we are being conformed to, what kind of conformation is taking place, and what produces it. Scripture distinguishes between being conformed to the image of Christ, being transformed through the renewal of the mind, and being conformed to the temporary pattern of the present world.

This distinction is important because the English word conformed can conceal a significant difference in Paul's language. In Romans 8:29, Paul uses symmorphos (σύμμορφος), describing those who are predestined to be conformed to the image of God's Son. In Romans 12:2, however, Paul uses syschēmatizō (συσχηματίζω, "together with") when he warns believers not to be conformed to this world. The words are related to different concepts of form: symmorphos is associated with morphē, while syschēmatizō is associated with schēma. This distinction should not be pressed beyond what the words themselves establish, but it does provide an important theological contrast. Together with speaks to the heart, who or what is the object of conformation. Paul can speak positively of a Christlike conformation while simultaneously warning against a worldly conformation because these are two entirely different directions of formation.

Romans 8:29 places conformation to Christ within God's eternal purpose for His people. Paul writes that those whom God foreknew He also predestined “to be conformed to the image of his Son.” The object of this conformation is therefore not a religious system, a denomination, a cultural standard, or an external code of conduct. The scriptures are clear these are all elemental principles that do not change us inwardly. God has determined that His people will ultimately bear the likeness of Christ. The Christian life is consequently not God's abandonment of a person after justification, leaving him to determine for himself what holiness should look like. The God who saves is also the God who conforms His people to the image of His Son.

This is fundamentally different from attempting to manufacture righteousness through external conformity. Legalism seeks to establish righteousness by means of requirements imposed upon the person from the outside. It can produce recognizable religious behavior without producing the character that behavior is supposed to express. Scripture certainly does not condemn obedience, because obedience belongs to the Christian life; what Scripture condemns is the substitution of external religious conformity for the righteousness that God produces within His people. The Pharisees provide a particularly clear example of this problem. They could carefully regulate outward conduct while the condition of the heart remained corrupt, which is why Jesus could describe them as cleaning “the outside of the cup” while the inside remained full of greed and self-indulgence (Matthew 23:25).

The New Covenant reveals that God's work goes deeper than external regulation. Through Jeremiah, God promised a covenant in which He would put His law within His people and write it upon their hearts (Jeremiah 31:31–34). Through Ezekiel, He promised, “I will give you a new heart, and a new spirit I will put within you” (Ezekiel 36:26). God was not merely promising to provide Israel with better instructions. He was promising to change the people themselves. The righteousness that belongs to the New Covenant therefore cannot be understood merely as an external standard imposed upon an unchanged person. God changes the heart, gives His Spirit, and produces a new kind of life from within.

This is where transformation becomes essential to understanding conformation. Romans 12:2 does not merely tell believers what not to do; it gives the positive alternative: “be transformed by the renewal of your mind.” Paul uses metamorphoō (μεταμορφόω), a word describing a change of form. The transformation he describes is connected specifically to the renewal of the mind, which means that the Christian's life is being changed at the level of understanding, perception, judgment, and desire. The gospel does not merely teach a person to behave differently while leaving his understanding of God and righteousness untouched. Through the renewing work of God, the person increasingly comes to see reality according to the truth of the gospel and consequently lives differently.

Transformation and conformation therefore belong together, but they are not identical concepts. Romans 8:29 identifies the destination: conformity to the image of the Son. Romans 12:2 identifies an important aspect of the process: transformation through the renewal of the mind. The believer is not being transformed so that he can invent his own image; he is being transformed into conformity with the image God has already established in Christ. The renewed mind increasingly recognizes what belongs to Christ and rejects what belongs to the world. Transformation is therefore not simply self-improvement. It is the work by which the life of the believer increasingly corresponds to the reality of Christ.

Paul's warning not to be conformed to the world must consequently be understood in contrast with this Christward work. The world has its own schēma, its own pattern and order. It constantly presses people toward particular definitions of success, identity, pleasure, power, wealth, status, morality, and significance. Much of this conformity happens without conscious intention. People absorb the assumptions of their culture simply because they live within it. The danger for the Christian is not merely that the world will persuade him to commit obvious acts of sin. The deeper danger is that the world will gradually reshape his understanding so that its values become normal and God's values become strange.

This is why Romans 12:2 connects the refusal to conform to the world with the renewal of the mind. Paul does not tell believers merely to construct a different outward appearance. How would this be different from living to written code? How does Jesus saying if you obey my commandments you will abode in my love differ? Paul is saying avoid the world's pattern and to undergo transformation "be renewed in the spirit of your mind." What believers have that the world does not is God's Spirit within. Living in this new living way, not written code, changes behavior.

The Christian therefore does not escape worldly conformity merely by adopting Christian clothing, vocabulary, customs, or religious practices. A person can change his outward appearance while continuing to think according to the world's carnal mind. Genuine transformation reaches beneath the outward appearance and changes the way the person understands and responds to life.

This also explains why it is inaccurate to equate all external obedience with legalism. The fact that righteousness becomes visible in outward conduct does not make that conduct legalistic. Love has outward actions. Mercy has outward actions. Patience, forgiveness, generosity, sexual purity, humility, and service all become visible in the way a person lives. The issue is not whether the transformed life eventually produces outward obedience. It certainly does. The issue is whether outward behavior is being used as a substitute for inward righteousness or whether it is the genuine fruit of the work God has accomplished within.

The difference can be seen in the relationship between fruit and the tree. A healthy tree produces good fruit because of what it is, not because someone has attached artificial fruit to its branches. Likewise, the Christian life is not supposed to consist of attaching religious behaviors to an unchanged heart. The outward life is meant to express the inward work of God. This does not eliminate obedience; rather, it gives obedience its proper foundation. The believer does not obey in order to create the new life. He obeys because God conforms the person to be like Jesus. 

Consequently, there is a profound difference between external imitation and Christlike transformation. A person can imitate certain behaviors associated with Jesus without actually being transformed in his character. We can adopt good principles like what would Jesus do. We can learn Christian language, adopt Christian customs, participate in Christian activities, and conform to the expectations of a religious community while remaining governed by pride, greed, fear, resentment, or the desire for human approval. Such conformity may look religious, but appearance alone cannot establish that the person has been conformed to Christ. God's purpose is much deeper: He is producing the likeness of His Son in His people.

This distinction also protects the doctrine of grace from two opposite errors. On one side is legalism, which attempts to produce righteousness by external conformity. On the other side is a distorted understanding of grace that treats the absence of legalism as permission for the believer to remain unchanged. Neither position represents Paul's teaching. Grace does not mean that God leaves His people untouched; grace means that God accomplishes in His people what they cannot accomplish by their own strength. The Spirit gives life, renews the mind, produces holiness, and conforms believers to Christ. The transformation of the believer is therefore not a rival to grace but one of grace's great effects.

The distinction becomes especially clear when we consider the direction of formation. The world says, in effect, that the individual should take his shape from the values surrounding him. God's purpose is the opposite: the believer is to receive his ultimate form from Christ inward. One pattern is temporary; the other is eternal. One is imposed by the changing standards of the present age; the other is established in the Son. One seeks to make the person resemble the world around him; the other is God's work of making His people resemble Christ.

The Christian therefore cannot simply ask whether he is changing. Everyone is changing, and everyone is being shaped by something. The more important question is what image is determining the shape of his life. If the world determines his values, ambitions, definitions of success, and understanding of fulfillment, he is being conformed to the world. If Christ increasingly determines his understanding of love, righteousness, holiness, humility, service, and obedience, then God's Christlike work is becoming evident in him. The issue is not whether formation is taking place, but whether the formation is according to the pattern of the world or according to the image of the Son, which the latter is according to God's purpose.

Fatally, religious activity can dwarf this conformation and even send people blindly to hell (Matthew 7:21-23). When we make it all about outward change, even outward "outreach" we risk that danger and are warned. Evangelism is just one gift given to the church to grow it into maturity to be like Christ. We do outreach, but we don't make it all about outreach. That's so clear in the scripture, be good to all people, but especially to the family of the God. Jesus said we'd be known as His disciples because we love one another. What fulfills the law is loving God and loving your brother. But the carnal man has no power to fulfill it. We love God because he first loved us. His power within us empowers us to fulfill the righteous requirements of the law, as we live according to the new living way of the Spirit, not written code.

Jesus said if we obey His commands, we abide in His love. Without transformative work of the Spirit, this could be seen as just living to commands or principles, and conformation outwardly to a religious system, which is just another form of walking in the flesh. Jesus gives us the difference and John the sign of a true church, between just living to commands and transformative behavior; "I give you a new command, love one another as I loves you." This is not another form of written code because it who we become, his laws written on our hearts and put in our minds as we are epistles of a living God, becoming like him.

Romans 8:29 and Romans 12:2 therefore provide a coherent picture of God's work in the believer. God has predestined His people to be conformed to the image of His Son, while Paul commands those same people not to be conformed to the pattern of this world. Between these two forms of conformation stands the transforming work of the renewed mind. The believer is called to reject the world's pattern precisely because God is producing another pattern within him—the likeness of Christ.

There is a righteous conformation and there is a worldly conformation. There is the conformation to the image of Christ that God has purposed from eternity, and there is the conformation to the temporary pattern of this present age that scripture commands believers to resist. There is also transformation, the renewing work through which God changes the mind. a proving that brings the believer's life into correspondence with Christ. The answer to worldly conformity is therefore not the construction of a different external mask, but the deeper work of God that transforms the person from within.

The danger is that the church can reproduce a system that conforms people outwardly. The very thing Jesus condemned in the Pharisees: an outward religious form without an inward transformation of the heart. Jesus gives us a terrifying warning that even those who prophesy, cast out demons, and perform mighty works in His name hear, “I never knew you; depart from me, you workers of lawlessness” (Matthew 7:23). Busy in religious matters, but ultimately workers of lawlessness. The issue, therefore, is not whether there is an outward expression of obedience, but whether that outward expression is flowing from a heart that God has transformed and is conforming to the image of Christ. 

If the church makes external conformity its focus, it can create people who look religious without becoming like Jesus, leaving them spiritually immature, vulnerable to being “tossed to and fro” by every wind of doctrine, and unable to discern the deceitful schemes that surround them (Ephesians 4:14). God looks at the heart, and the work of ministry is for the growth of His children. When the church loses that focus, it does not merely fail its members; it damages its witness before the world.

Paul doesn't merely give us the command to change; Scripture gives us a divine pattern and a destination. Ephesians 4:13 says the ministry of the church is directed toward maturity, “to the measure of the stature of the fullness of Christ,” while Ephesians 4:15 says that we are to grow up “into him who is the head, into Christ.” The measure of Christian conformity, is maturity which looks like Jesus, which is therefore not how closely someone conforms to a religious culture, but how fully his life is being brought into the likeness and fullness of Christ.

That also makes Jesus's warning about this much more powerful. The church itself can become a conformity-producing environment. People can learn how to conform to the expectations of the congregation, denomination, ministry culture, or religious system without actually growing into Christ. They may know what Christians are supposed to say, wear, do, oppose, support, and believe, yet still remain immature because the goal has subtly shifted from growing into Christ to conforming to the group.

The ultimate purpose is that Christ Himself would be seen in His people. God is not merely making Christians look different from the world; He is conforming them to the image of His Son. That work begins with God's grace, proceeds through the renewing work of the Spirit, changes the mind and heart, and increasingly becomes visible in the believer's conduct. The Christian is therefore not to conform to any system that fits the world's pattern. s mind, and to be conformed to the image of Jesus Christ.

Deep Dive 

Until the church obtains, "unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ (Ephesians 4:11–13)" “Stature” is not merely saying that Christians should become mature in a general sense. Paul gives a specific measure by which maturity or perfection, τέλειος (teleios), is measured: Christ Himself.

In Ephesians 4:13, the word translated “stature” is Greek hēlikia (ἡλικία). It can refer to age, maturity, or stature, depending on context. Here Paul uses it in the expression “the measure of the stature of the fullness of Christ.” The idea is not external. Paul is describing the full-grown condition or mature measure that corresponds to Christ.

The fascinating thing is that Paul gives us several measurements in this passage. The ministry gifts are given to equip the saints, the saints are equipped for the work of ministry, the body is built up, and the goal is that believers arrive at the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ (Ephesians 4:11–13). So Paul isn't leaving “maturity” undefined. He gives us the measuring standard.

Christ is the measure.

That makes “stature” much richer than simply saying, “We need to grow up.” Paul is saying, in effect, How do you know whether the church has reached maturity? Measure it against Christ. The question isn't whether the church has become large, organized, educated, influential, successful, or externally impressive. The question is whether the body is growing toward the fullness that is found in Christ.

Romans 8:29 explicitly gives us “the image of his Son.” Ephesians 4:13 gives us “the stature of the fullness of Christ.” But the two ideas fit together extraordinarily well. Romans tells us the believer's predestined conformity: the image of the Son. Ephesians tells us the measure toward which the church grows: the stature of the fullness of Christ. Then Ephesians 4:15 makes the direction explicit: “grow up in every way into him who is the head, into Christ.”

Conformed to the image of the Son → transformed → grow up into Christ → measured by the stature of the fullness of Christ.

And the point about symmorphos is even more significant. The issue isn't merely, “Are we conforming?” Scripture says we are supposed to be. The issue is what is the measure of that conformation? If Christ is the measure, then Christian maturity cannot be measured by conformity to a religious culture. We can become extremely proficient at looking like the church and still fail to grow up into Christ.

That is precisely where your Pharisee example becomes powerful. They had an external religious form, but Jesus exposed the fact that the inside was not corresponding to the outside. Their measure had become external religion rather than the character and righteousness God desired. In Ephesians, however, Paul gives the church a completely different measurement: “the measure of the stature of the fullness of Christ.”

And there's another beautiful connection here. Paul doesn't say that the church invents the measurement. Christ is already the measure. We don't decide what Christian maturity looks like and then conform ourselves to that definition. Christ defines the maturity toward which His body is growing.

So I think the question emerging from your essay is becoming very strong:

What is the measure of our conformation?

Are we measuring ourselves by the world? By a denomination? By a ministry culture? By outward religious behavior? By traditions and expectations? Or is Christ Himself—the stature of His fullness—the measure?

That gets right to the heart of what you're trying to say. The problem isn't conformation. The problem is conforming to the wrong measure.

The Work of Ministry in Conforming to Christ

The evangelist is explicitly named among the gifts Christ gave to His church (Ephesians 4:11), but Paul does not say that the purpose of the evangelist is to make the whole church into evangelists. Nor does he say that the purpose of the apostles, prophets, evangelists, pastors, and teachers is simply to keep everyone busy doing ministry. He gives the purpose in the next verses: “to equip the saints for the work of ministry, for building up the body of Christ” (Ephesians 4:12). Then he gives the ultimate measure: “until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ” (Ephesians 4:13).

That changes the entire way we should read the gifts.

Evangelism matters. Outreach matters. The proclamation of the gospel matters. But evangelism is not the final purpose of the gifts. It is part of the ministry through which Christ builds His body toward maturity. The same is true of teaching, shepherding, prophecy, apostleship, and the other gifts Paul discusses elsewhere. The gifts are diverse precisely because the body is diverse. First Corinthians 12 makes this point forcefully: the body has many members, with different functions, and no individual member is the whole body. Paul even challenges the idea that everyone should perform the same function by asking, “Are all apostles? Are all prophets? Are all teachers? Do all work miracles?” (1 Corinthians 12:29).

So when the church says, “We are all evangelists,” “We are all hands and feet,” or “Everything is about outreach,” there can be something true underneath those statements, but they can also flatten Paul's teaching about the body. Every believer is certainly called to bear witness to Christ in the life God has given him, but that does not mean every believer possesses the gift of evangelism. Likewise, the fact that Paul uses the body metaphor does not mean that every member performs every function. The beauty of the body is that Christ supplies different members with different functions, and those functions work together toward one purpose.

And that purpose becomes even clearer when you read Ephesians as a whole. Ephesians is not ultimately a manual for discovering one's ministry niche. Paul begins with God's eternal purpose in Christ, the blessing of believers in Christ, adoption, redemption, the inheritance, and the sealing of the Spirit. He then moves into the mystery of God's purpose to unite all things in Christ and to create one new humanity in Him. By chapter 4, the gifts are functioning within that much larger purpose: Christ is building His body into maturity and unity under His headship.

That is why Ephesians 4:15 is so important: “speaking the truth in love, we are to grow up in every way into him who is the head, into Christ.” The direction of ministry is not merely outward toward more activity; it is also upward and inward toward Christ. The body is being built up so that it grows into its Head. Evangelism brings people into the body, teaching establishes them in the truth, shepherding cares for them, and the various ministries serve the body—but the destination is Christlikeness and maturity.

And that connects directly to the conformation question we've been developing. If the church measures success primarily by outreach, numbers, activity, programs, or external religious conformity, it can completely miss Paul's measurement. Paul's measurement is Christ. The church is mature when it is growing “into him,” and the measure of that maturity is “the stature of the fullness of Christ.” The gifts are therefore not ends in themselves; they are instruments Christ gives to His body so that His people may be equipped, built up, unified, protected from deception, and brought into maturity according to His image.

That also explains why Paul immediately contrasts maturity with being “tossed to and fro” by every wind of doctrine. A church can be extraordinarily active and still be immature. It can evangelize, organize, build programs, and perform religious works while its people remain spiritually unstable and vulnerable to deception. Paul's answer isn't simply more activity. His answer is that the body must grow up into Christ.

This gives Ephesians 4:11–16 its proper place in the larger argument. The gifts are not primarily about making everyone perform the same ministry. They are about Christ supplying His body with what it needs so that the whole body grows toward one measure—the fullness and stature of Christ. And that brings us right back to Romans 8:29: the destiny of God's people is to be conformed to the image of His Son.

The larger biblical picture, then, is not “What ministry am I doing?” but “Is the ministry of Christ producing the maturity of Christ in His body?” That is a much greater purpose.
