Our "death to sin" ([Rom.] 6), the indwelling power of the Holy Spirit (ch. 8), and the renewal of our minds (12:1-2) will inevitably mean that we sin less and less. Yes, we will never become sinless, but we certainly sin less.
So Paul took his stand in the open space at the Areopagus and laid it out for them: "I'm here to introduce you to this God.... He doesn't play hide-and-seek with us. He's not remote; he's near. We live and move in him, can't get away from him!" ~Acts 17
