We’ve all sinned, done some things that were against God’s commands, things that grieved Him. Did you ever try to cover up a sin that you knew was terribly wrong, or pretend that it never happened? Our psalm for this week was written about just such an event, and the repentance, cleansing, and restoration that followed.
The superscription for this psalm gives us the context, as King David wrote this after having been confronted by the prophet Nathan following having committed adultery with Bathsheba, the wife of Uriah, one of David’s elite soldiers (I Samuel 11 - 12:15). When they found out that she was pregnant, David ordered his general, Joab, to put Uriah in the thickest part of the battle, and then retreat, essentially ordering his execution. So David committed two grave sins - adultery and murder. Then David married Bathsheba, and acted for over a year as if nothing had happened. However, God knew, and when David was not repenting on his own, He sent Nathan to confront him.
The king could have had Nathan killed for daring to confront his sin, but David knew he had done wickedly in the sight of God, and immediately repented and cried out to God for forgiveness (vs. 1-2). He knew that he could not fix this, and he cried for God’s mercy, which is undeserved. Forgiveness is grounded in who God is, not who we are.
David made a full confession of his sins (vs. 3-4). He didn’t try to hide it any longer, make excuses, or give a partial confession. He was aware of the gravity of his sin, and took responsibility. He also acknowledged that his offense was against God. Whenever we sin, our sins are against God and His holiness. This does not deny the harm done to others. Rather, it recognizes that all sin is ultimately rebellion against God.
He confessed not only his acts of sin, but also that he, like all of us, had a sinful nature (vs. 5-6). God desires that we are truthful to both Him and ourselves. The Lord wants integrity, not outward religiosity.
Our psalm continues with a picture of sacrificial imagery (vs. 7). Hyssop was a plant used to sprinkle water and the blood of sacrifice, which is an image of cleansing. David was asking for cleansing through atonement. Even though I really dislike winter and snow, snow can be a picture of our forgiveness. Jesus provided a way for us to be cleansed of our sins, and our hearts to be made whiter than snow. Only He can cleanse the sinner, and He does so thoroughly. There is only one way to deal with our sin problem, and that is the Precious Blood of Jesus.
In verse 10 David prayed that God would “Create in me a clean heart.” The word “create” in Hebrew is “bara”, which is the same verb used in Genesis 1 when God created the heavens and the earth. David was asking for a divine act of re-creation. He wanted God to make him into a new man. David prayed that God not cast him away, nor take His Holy Spirit from him (vs. 11). This was not about losing his salvation, as we cannot lose our salvation. This was about losing the empowering presence of God for service, such as what happened with the previous king, Saul.
David prayed that the joy of the Lord that he once felt would return (vs. 12). Sometimes we struggle with self-forgiveness because we find it difficult to accept God’s forgiveness. Guilt can be so strong that it overshadows God’s gift of forgiveness. Often our personal disappointment prevents us from forgiving ourselves, especially when we see the results of our sin. However, David knew that when God forgives, we are truly forgiven, and we can move on in our life by further service to Him (vs. 13).
Rituals alone cannot fix sin (vs. 16-17). God wants heart-level repentance rather than just an outward show. Repentance involves full confession, and a true confession will acknowledge our guilt. It involves recognizing that the sin was against God, even though other people may be hurt, as well. When we repent, we take full responsibility for our sin. There can be no blaming others or making excuses with God. It is not complete without full honesty. Repentance means changing one's mind about sin.
It was at David’s lowest point that he had a revelation of God’s love and mercy. God does not abandon us in our times of crisis, for He has promised to save us, even in our darkest time. Psalm 51 is a gift to every believer who has ever failed, which is all of us. It shows that no sin is too deep for God’s mercy, and no heart is too broken for God to restore. David’s darkest moment became the occasion for one of Scripture’s brightest testimonies of grace.
