Paul begins Ephesians 4 with a simple appeal: “live your life in a way that is worthy of the call you have received from God” (v. 1, CEB). For the first three chapters, Paul has been describing what God has done. We have been chosen in Christ, saved by grace, brought near through the cross, made members of one household, and joined together as a dwelling place for God through the Spirit.

Now Paul turns toward the question that naturally follows: If this is who we are because of grace, how should we live? His answer doesn’t begin with private spiritual disciplines or individual morality. He begins with how we live with one another: “Conduct yourselves with all humility, gentleness, and patience. Accept each other with love, and make an effort to preserve the unity of the Spirit with the peace that ties you together” (vv. 2–3). The calling we have received creates a people.

There is one body, one Spirit, one hope, one Lord, one faith, one baptism, and one God. Christian unity isn’t something we manufacture by pretending differences don’t exist. It's something God has already created in Christ, and Paul tells us to guard it carefully. But unity does not necessarily mean sameness.

Christ gives different gifts to the church. Apostles, prophets, evangelists, pastors, and teachers are named here, but Paul’s concern isn’t creating a hierarchy of important Christians. Their purpose is “to equip God’s people for the work of serving and building up the body of Christ” (v. 12). The ministry belongs to the whole church.

Pastors aren’t called to do Christianity on everyone else's behalf. Teachers don’t study so everyone else can remain spiritually immature. Christ gives gifts throughout the body so that the entire body can grow.

Growth is the point. Paul says we are to grow toward maturity, becoming increasingly like Christ. Otherwise, we remain vulnerable—“tossed and blown around by every wind that comes from teaching” (v. 14). That image feels especially relevant in a world overflowing with voices claiming to tell us what is true. We can move quickly from teacher to teacher, video to video, controversy to controversy, always reacting to whatever catches our attention next.

Christian maturity gives us roots. It teaches us to recognize the voice and character of Jesus. It helps us test what we hear against Scripture. It forms us into people capable of holding truth and love together. Paul doesn’t tell the church simply to speak truth. We are to speak “the truth in love” so that together we “grow in every way into Christ” (v. 15).

Truth without love can wound. Love without truth can lose its direction. Christlike maturity refuses to separate them. Then Paul makes the calling intensely practical. Growing into Christ means taking off the old way of life and putting on the new.

Tell the truth. Deal honestly with anger. Work so that you can share with someone in need. Use words that build people up. Put away bitterness, rage, shouting, and insults. Be kind. Be compassionate. Forgive as God has forgiven you in Christ.

These aren’t random rules tacked onto a theological letter. They are what the new humanity looks like when grace becomes visible in everyday relationships. This is holiness worked out in community.

God’s grace doesn’t only forgive what we have been. The Holy Spirit renews the way we think, speak, work, respond, forgive, and love. We cooperate with that grace by taking off habits that belong to the old life and practicing ways of living that resemble Jesus. And we do this together.

Paul’s picture of maturity is not a collection of impressive individual Christians standing beside one another. It is a body “joined and held together” in which every part does its work, and the whole body “grows so that it builds itself up with love” (v. 16). That means my growth affects you. Your gifts strengthen someone else. Our words can either weaken the body or help it grow. Our patience, forgiveness, generosity, and kindness are not insignificant acts of personal virtue. They are part of how Christ builds the church.

So living worthy of our calling does not mean proving that we deserve what God has given us. We could never do that. It means allowing the grace we have received to shape the people we are becoming. And Paul gives us the measure of maturity: not accomplishment, influence, knowledge, or reputation. Christ. The goal is that together, by grace, we grow up into him.

Choose one relationship today in which you can help build up the body of Christ. Speak one truthful and gracious word, extend forgiveness, offer encouragement, or use one of your gifts to serve that person.
