O loving and kind God, have mercy. Have pity upon me and take away the awful stain of my transgressions. Oh, wash me, cleanse me from this guilt. Let me be pure again. For I admit my shameful deed-it haunts me day and night. It is against you and you alone I sinned and did this terrible thing. You saw it all, and your sentence against me is just. Create in me a new, clean heart, O God, filled with clean thoughts and right desires. Don’t toss me aside, banished forever from your presence. Don’t take Your Holy Spirit from me. Restore to me again the joy of your salvation, and make me willing to obey you.
(Psalm 51:1-12 TLB)
