“Our body of sin has been done away with,” Romans 6 tells us. “Wow! My flesh is finally dead!” Yet deep down it’s really hard to believe, because “our body of sin” being ”done away with” doesn’t actually mean what we think. Our sinful flesh didn’t go anywhere. It’s clinging close at hand. This can be very disheartening, because we find ourselves continually bombarded by a sense of guilt—made all the worse by Satan’s accusation and deceit.
        Yet even though we have to drag that old baggage around in our new life in Christ, God has solved our dilemma. He truly did cause our old self to die, for our sinful flesh has now become a non-issue in His eyes. “Doing away with our body of sin” literally means that our flesh has been rendered powerless. Jesus got rid of the problem for us!
