Have Mercy on Me: Sin Confessed before God
Psalm 51’s superscription connects the prayer with David after Nathan confronted him over Bathsheba. The poem begins not with excuses but with God’s mercy, lovingkindness, washing, and cleansing. “Against thee, thee only, have I sinned” does not erase the real human victims of David’s sin; it recognizes that every sin is ultimately rebellion against God.
Romans 3:4 directly quotes Psalm 51:4 while defending God’s righteousness and truthfulness. Verse 5’s language about being shaped in iniquity is theologically important, but this verse by itself should not be made to settle every later debate over original sin or inherited guilt.
