Ephesians 4:21 meaning

In this verse, Paul emphasizes that true learning in Christ diverges fundamentally from the unredeemed way of life. The Ephesians, previously steeped in the ignorance and futility that characterized the Gentiles around them, have now been taught the transformative truth found in Jesus. Paul asserts that the knowledge they received is not merely intellectual; it is rooted in a relationship with Christ that compels a change in lifestyle. This "truth in Jesus" serves as both a revelation of God's will and a catalyst for personal transformation.

This plea is particularly profound as it calls Christians to reject their old ways—not merely to avoid sin for sin's sake but to embody the righteousness that stems from their relationship with God. As believers, they are urged to discard their former selves and embrace the new identity shaped by Christ’s own life and character. The essence of the gospel thus motivates them to live differently, illustrating that true discipleship is evidenced by a commitment to walk in the light of Christ's truth. This perspective aligns with the ongoing need for renewal in the believer's mind and spirit, echoing the overarching theme of sanctification found in other passages .
