51:1-2 Plea for mercy
51:3-6 David confronts how horrible his sins are
51:7-9 He pleas for complete forgiveness
51:10-12 Create in me a clean heart
51:13-17 God wants a whole hearted repentance
51:18-19 He asks God build Zion
The things David requests: God's mercy, blotting out of sins, washing, cleansing, created anew all find their greatest fulfillment in Jesus
