Romans 5:17

For if by the trespass of the one (Adam), death reigned through the one (Adam), much more surely will those who receive the abundance of grace and the free gift of righteousness reign in (eternal) live through the One, Jesus Christ.

The devil will try to remind us of our sins and failures constantly. The barrage of criticism is a way to keep us feeling unworthy and unable to move forward spiritually. Paul reminds us that we were made righteous, our sins removed, and we are to reign through Jesus Christ. Therefore, we must stand on our faith, remind ourselves we are not the downtrodden sinner and move forward and leave the past behind.
