Have mercy on me Oh God!

“Cast me not away from Your presence; and take not Your holy spirit from me. Restore unto me the joy of Your salvation; and uphold me with Your free spirit. Then will I teach transgressors Your ways; and sinners shall be converted unto You. Deliver me from blood-guiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of Your righteousness. O Lord, open thou my lips; and my mouth shall shew forth Your praise.”
