In Ephesians 4:20–32, Paul calls believers to a radical transformation rooted in the truth found in Jesus. This passage outlines a spiritual journey: putting off the old self corrupted by deceitful desires, being renewed in the spirit of the mind, and putting on the new self-created in righteousness and holiness. The new self is not just a concept—it’s expressed through tangible behaviors. Paul urges the church to speak truth, resolve anger quickly, work honestly, and reject corrupt speech. He warns against grieving the Holy Spirit and commands the removal of bitterness, rage, and malice. Instead, believers are to embody kindness, compassion, and forgiveness, reflecting the character of Christ.
