"Create for me a pure heart, Lord, and renew a steadfast spirit in me. Do not cast me from your presence or turn the Holy Spirit from me. Restore the joy of your salvation and grant a willing spirit to sustain me. Then I will help others to see your ways, so that your people may return back to you... You do not desire grand gestures or burnt offerings. The sacrifice of the Lord is a broken spirit; it is a broken and contrite heart that you, my God, will not refuse."
Psalm 51:10-17
