Remember when computers had "go back" buttons? It would automatically take you back to a previous date and wipe out all the bad stuff you'd loaded on your computer.
God has a go back option. It's found in I John 1:9. It reads, "If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness."
That's not all He does. He removes our sins as far as the east is from the west. Psalm 103:12 says, "As far as the east is from the west, so far has He removed our transgressions from us."
I'm so glad He didn't say "as far as the north from the south," because we would eventually run into them again. If we go east around the whole globe, we never meet west at some point, so He's saying we'll never meet up with those sins again.
So, all we have to do is admit our sins to Him and He will cleanse us and make us right with Him. Now that's good news!
