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 was sinful at birth, sinful from the
time my mother conceived me. Surely you desire truth in the
inner parts; you teach me wisdom in the inmost place.
(Psalm 51:1-6 NIV)
