Psalms 32

Psalms 32:5  
I acknowledged my sin to You,  and I did not cover my iniquity. I said, I will confess my transgressions to Jehovah.  Then You forgave the iniquity of my sin. Selah

Psalms 32:7  
You are my hiding place; You preserve me from trouble; You surround me with the ringing shouts of deliverance. Selah

In the beginning of this psalm David confessed his sins (vv. 1-5), but at the end he justified himself as righteous and upright in heart. In reality, apart from Christ no one is righteous and upright in heart (Rom. 3:10; Jer. 17:9).

God’s forgiving our sins and not imputing iniquity to us are based on Christ’s redemption (Eph. 1:7). Apart from Christ’s redemption the righteous God cannot forgive our sins (Heb. 9:22).

David’s writing here is that of a person who tried to keep the law apart from Christ.

In His economy God does not want us to endeavor to keep the law. He wants us to live Christ, the God-man, that He may be magnified (Phil. 1:19-21a). To live Christ in order to magnify Him is to enjoy Him.
