This is very wise because he will quote David.
Blessing comes a part from works .
God is greater in grace than that. Blessed is the man whose sin the Lord will not take into account. Psalm 32 is a companion Psalm to Psalm 51, David's Psalm of confession after his sin with Bathsheba and his murder of her husband Uriah the Hittite. In both Psalms he is overwhelmed by the grace of God and forgiving him of his sin. We should also be overwhelmed at the graciousness of God.
