“Have mercy on me, O God,
according to Your unfailing love;
according to Your great compassion
blot out my transgressions.
Wash away all my iniquity
and cleanse me from my sin.
For I know my transgressions,
and my sin is always before me.
Against You, You only, have I sinned
and done what is evil in Your sight,
so that You are proved right when You speak
and justified when You judge.
Surely I have been a sinner from birth,
sinful from the time my mother conceived me…
Cleanse me with hyssop, and I will be clean;
wash me and I will be whiter than snow…
Create in me a pure heart, O God,
and renew a steadfast spirit within me.
Do not cast me from Your presence
or take Your Holy Spirit from me.
Restore to me the joy of Your salvation
and grant me a willing spirit to sustain me.
Then will I teach transgressors Your ways,
and sinners will turn back to You.

In Jesus' name. Amen.
