Of David. A Maskil.

How joyful is the one
whose transgression is forgiven,
whose sin is covered!
How joyful is a person whom
the LORD does not charge with iniquity
and in whose spirit is no deceit!
When I kept silent, my bones became brittle
from my groaning all day long.
For day and night your hand was heavy on me;
my strength was drained
as in the summer’s heat.
Then I acknowledged my sin to you
and did not conceal my iniquity.
I said, “I will confess my transgressions to the LORD,”
and you forgave the guilt of my sin.
(Psalm 32:1-5)

But to the one who does not work, but believes on him who justifies the ungodly, his faith is credited for righteousness. Likewise, David also speaks of the blessing of the person to whom God credits righteousness apart from works: Blessed are those whose lawless acts are forgiven and whose sins are covered. Blessed is the person the Lord will never charge with sin.
(Romans 4:5-8)

He traded my sin for His perfection.
