Jesus teaches that real transformation doesn’t come from managing behavior but from healing the heart. In the Sermon on the Mount, He exposes the roots beneath anger, lust, and broken relationships, showing that sin always starts long before it shows up on the surface. Kingdom living means treating every person as eternally valuable and fighting sin not just because it’s wrong, but because it hurts people. When Jesus pulls the roots into the light, He invites us to surrender—not just for forgiveness, but for lasting change.
