Sin seems like play until it catches you in its grip. David was trapped by his own sin, and to escape he committed more and grosser sin. But God's mercy was manifested to David to confront his sin, and to repent. It cost David the life of his son- the infant born of his sin, and later, the promised Son o who was both David's Son and David's Lord. We can learn from David's example that no saint is beyond falling, and no sinner is beyond redemption.
