In this powerful passage, Paul draws a sharp contrast between the life we once lived—shaped by ignorance, hard-heartedness, and self-centered desires—and the new life we've been called into through Christ. The "old self" is marked by corruption and deceit, while the "new self" reflects God's righteousness, holiness, and love. This teaching unpacks what it means to put off the old humanity and put on the new—practically, relationally, and spiritually.
