Psalm 51 (See our study on Psalm 32 and 2 Samuel 12)
David is living in light of Psalm 32.3-4 when Nathan the prophet walks into the palace. He confronts the man and David is released from the stronghold of sin as he works through the concept of this psalm.
Verses1-4-David doesn’t address God as the covenant God of Israel, Jehovah (יְֽהוָה), in this psalm. He addresses Him as the creator God, Elohim (אֱלֹהִים), or Lord (אֲדֹנָי) because of his unworthiness to regard himself as one of God’s own. David basis his forgiveness solely on whom God is not what David had done. This is the first step. David is contrite, remorseful over his sin. The second step is the confession of sin. It is admitting to God what He already knows and agreeing with Him that you are wrong. The third step is to admit you have nothing in yourself to deal with your sin; you need God.
As David stated, our sin is against God and Him alone. However, the consequences go far beyond and reaches to those we love. It hurts us. As describe in Psalm 32 and in this psalm, sin affects our bodies. David’s eyes, mind, ears, heart, spirit, and mouth were affected in the physical realm. David’s fellowship and joy with the Lord were affected in the spiritual realm. Sin hurts those we are to love. Tragedy strikes families (see 2 Samuel 11 and 2 Samuel 12 for our study on this).
Verses 5-12-David confesses that not only does he have a desire for sin but that he was born that was as is all humanity. Once he acknowledges this, David begins a progression in his prayer. He asks God to purge him, remove his defilement. He asks God to wash him, to cleanse him deeply. He asks God to let the bone He broke through discipline dance again. [I will link my sermon series on Dancing with Broken Bones at a later date.] He asks God to make him experience the joys of answered prayer. He asks God to not treat him according to His sins but to hide His face from them. He asks God to create in him a clean heart. This prayer is ultimately answered in Christ. As Christians, we have been given a new heart in Jesus. He asks God not to cast him away from His presence. He asks God not to take His Holy Spirit from him. This is a cry from the Old Testament as is evidenced with the Spirit of God left Saul that should not be on the lips of the saints in the New Testament. [If you desire more on this topic, let me know.] He asks God to restore to him the joy that can only be found in salvation. And lastly, David asks God to keep him from falling again.
13-17-David declares that he will live a life in which others will see and hear of God. Throughout this psalm David proclaims it is not what we can give but our humility before God. God delights in our coming to the Creator of the universe and learning from Him how to live the life for which we were created.
18-19-Praying for self to praying for the nation. Both are important and necessary for us to live the life God created for us to live.
Peter and Judas. David and Saul. Which one of the pairs are you? Judas and Saul were upset and saddened by their sin. Peter and David were repentant and saddened. They knew to whom to turn. They had hope. The former were without hope and God in this world (Ephesians 2.11-13).
Sin is complicated, but goodness is simple.
As in Psalm 32, there are basically three or four words that comprise the sin committed by David. The three mentioned in this psalm are the first of the four mentioned in Psalm 32. This is why David had to cry out to God for Him to have mercy on him.
