It is the only way out.
Sin still stings even though we have been given the victory over it. (I Corinthians 15:56)
lust=yearning for rebellion (I John 2:16)
Grace works in two ways
1. It covers us from the punishment of sin.
2. It enables us to keep from sinning anymore.
How does that work?
To walk by the Spirit (Galatians 5:16-18), and not by the flesh (Romans 7:15-24)
We can't do it by trying. These aren't fruits of our labors, but fruits of the Spirit.
You can't keep from sinning on your own, because sin is just too powerful.
As He forgives us, His words are “Go, and sin no more.”
