With sin being the problem forgiveness is the answer. Forgiveness is God's way of wiping sin from our records. He forgets our sin forever and ever. Micah 7 v18-19. This forgiveness is possible because of what Christ did on the cross.
Confession of sin paves the way for forgiveness.
Proverbs 28 v3. When you confess to the Lord he will forgive you. Confession is telling the Lord the He is right and you are wrong in the way you are living. You tell the Lord you are giving up your incorrect way and accepting his correct way. The forgiving of others is very important.
