There’s a single Greek word hiding behind one of the New Testament’s boldest promises, and once you take it apart, you can’t unsee what it demands of you. This week we dig into the word “transform,” from the Greek metamorphoo, the same root that gives us metamorphosis, and ask what it actually means for a Christian to change form rather than just change behavior. We trace it from Paul’s mirror image in 2 Corinthians 3 to the renewed mind of Romans 12, land on five specific, checkable ways James and Peter say that transformation shows up in a life, and ask whether what we’re chasing is real change or just a better disguise. Key verse: 1 Peter 2:9.
