Romans 4:6-8 :

Even as David also pronounces blessing on the man to whom God counts righteousness apart from works,

“Blessed are they whose iniquities are forgiven,
whose sins are covered.
Blessed is the man whom the Lord will by no means charge with sin.”

Abraham wasn’t the only one who was already aware of God’s grace. King David wrote about it in Psalms. In this case, Psalm 32. If the law was intended to be used as a way to get to God, why would a man be blessed “to whom God counts righteousness apart from works?” Wouldn’t that be the person who God doesn’t bless much? David wrote that a sinner is blessed by God when his sins are forgiven! What part does the law have in that? The law is the thing that makes the sin clear and declares the charges against the sinner. The law is not the thing that blesses us with forgiveness. David knew that the sacrifices covered the sins over. Now that Jesus has already died for the sins of the world, we know that our sins have now been more than simply covered. They have been completely removed because Jesus provided the only sacrifice that was able to remove sin completely.

God has blessed the world by giving us a way to have the charges of the law dropped so that we can live guiltlessly and have a new life. Striving to follow the works of the law does not bring a blessing but a curse. People who say they are blessed by the law are not really following it. David knew what it was like to need forgiveness, and he also knew what it was like to receive it.
