Forgive yourself

Once you have asked God for forgiveness, He forgives. He wipes the slate clean.

"If we confess our sins, He is faithful and righteous to forgive us our sins, and to cleanse us from all unrighteousness."

It then is important to forgive yourself. It may have been a really bad sin, and it's so hard to forgive ourselves. Sometimes we keep punishing ourselves, and hurting ourselves, thinking (often subconciously) that we deserve it.

But God is true to His word. Once you're sorry and repent, He has forgiven.

Then it's up to you.
