How do I forgive myself and move past shame over my past?

There is a crucial difference between guilt and shame. Guilt says “I did something wrong” and can be dealt with through confession and forgiveness. Shame says “I am something wrong” — and that is a lie the enemy loves to whisper. The cross answers both. If you have confessed your sin to God, He has forgiven it completely and remembers it no more. To keep punishing yourself is, in a sense, to say the cross was not enough. Receiving forgiveness is itself an act of humility — accepting that Christ's payment covers what yours never could. “Forgiving yourself” really means agreeing with God's verdict over your own feelings: in Christ you are a new creation, not your worst moment. When shame accuses, preach the gospel back to yourself. Scripture: Romans 8:1 — “There is therefore now no condemnation to them which are in Christ Jesus.” Take this step: Confess any specific unconfessed sin honestly to God and receive His forgiveness as final. Each time shame returns, answer it out loud with Romans 8:1.
