God's Mercy

Create in me a clean heart, O God; and renew a right spirit within me. Cast me not away from thy presence; and take not thy holy spirit from me. Restore unto me the joy of they salvation; and uphold me with thy free spirit.
Psalm 51:10-12,
For thou desirest not sacrifice; else would I give it: thou delightest not in burnt offering. The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wild not despise.
Psalm 51:16-17
