Mine Iniquity Have I Not Hid -- Psalm 32

Psalm 32 is the record of David’s battle with repentance. David full well knew that he had sinned with Bathsheba and knew he had sinned by arranging for the murder of her husband Uriah.
The stress of his sins affected David physically. Right down to his bones did David feel the ache of conviction about his sins. David ached. His body ached and his soul ached. Sin should weigh heavily upon the mind of the Christian. Your unconfessed sins should cause your bones to wax old.
