The Physical Pain of Unconfessed Sin

Psalm 32:3-5 When I kept silent, my body wasted away through my groaning all day long. 4 For day and night Your hand was heavy upon me; my vitality was drained away as with the fever heat of summer. Selah. 5 I acknowledged my sin to You, and my iniquity I did not hide; I said, “I will confess my transgressions to the Lord”; and You forgave the guilt of my sin. Selah.

Reflecting upon his past, David speaks of the time when he “kept silent” about his sins prior to his confession and repentance. Obviously the guilt of his sin was eating away at his conscience, and as a result, his “body wasted away through…groaning all day long.” Though he knew he had sinned, his silence means that he thought no one else knew about it. Not wanting to talk about it, hoping it would just go away, David’s physical body wasted away from the guilt of his sin. The word for “body” in v. 5 is literally “bones” in Hebrew. In other words, what had occurred spiritually was affecting him physically, and he could literally feel it in his body. This psychosomatic experience is common in people with a conscience, and it shows just how connected the mind is with the body and how the physical body can suffer from mental and spiritual stress. The term for “groaning” is the same word used for a lion’s roar except in this case it deals with the inner turmoil over one’s guilt. It is clear from v. 3 that David’s sin with Bathsheba weighed heavily upon him “all day long,” never allowing him a moment of peace.

Commenting on v. 3, David says in v. 4 that he could not escape God’s heavy hand upon him for his sin, for his conscience reminded him every day what he had done. Of course God’s “hand” is an anthropomorphism—giving human qualities to God who has no human form but is spirit (John 4:24). Albeit, David’s conscience felt the literal weight of God’s hand grasping his life with a firm grip. He knew that God did not take rebellion lightly, for he had observed God’s heavy hand upon Saul’s life before him. Now, however, David felt Saul’s pain and anguish, and his “vitality was drained away as with the fever heat of summer.” Since the word for “vitality” is “moisture,” David speaks of God’s heavy hand on him like the hot sun bearing down on him in the middle of summer, daily feeling more and more lethargic and without hope, lifeless and sapped of energy. Upon saying this, he follows with the Hebrew “Selah” which points to a “pause” after a thought. He may have wanted readers to pause and reflect upon what he has said, pondering for a moment the magnitude of the truth regarding unconfessed sin and its effects.

In v. 5 David reflects on how his guilt brought him to finally confess his sin to God. Once he hit rock bottom he told God what God already knew, namely, that he had sinned greatly. First, David “acknowledged” his sin. Literally, “I knew to You my sin.” David thus took full responsibility for his transgression, openly admitting to everything he did. Second, knowing that his “iniquity,” or punishment, was deserved, he did not attempt to “cover it” by making excuses for himself. In short, David told God what He already knew by confessing his transgressions and agreeing with God about the nature of them. Though he had sinned against Bathsheba and her husband, he confessed his sins to God, for it was God he had sinned against (cf. Ps 51:4; 2 Sam. 12:13). This is why David is able to say that God forgave the guilt of his sin, taking it away and remembering it no more. David was therefore relieved and able to live in God’s blessedness.

Food For Thought
Perhaps the mental illnesses with which we suffer are because of guilt, not being able to let go of the remorse we feel for something we have done in the past. This “disease,” as it is called today, does indeed have a cure, for those who confess to God and repent of what they have done will be forgiven—no matter what they’ve done! If we confess our sins, God is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness (1 John 1:9).
