David may have penned the psalm but Jesus is the one who embodied it. His blameless life was cut short by wicked evil doers whose deceit did not triumph for the glory of the Lord, high and lifted up on the cross, was vindicated by the empty tomb. But what of David singing this psalm having raped Bathsheba and murdered Uriah? (There is no choice when the king commands you come to his bed or go to war) Maybe the testing and the trying and the proving of David’s heart and mind is in the nature of his life which might have remained “blameless” as a simple shepherd but was destined for tragedy as a king. When by the prophet’s ploy “you are the man” God confronts David’s deceit and hypocrisy he does not defend himself but rather relies fully on the unfailing love of God who is just in judging and right in pronouncing guilt. Maybe in showing undeserved mercy to David God also repents of plucking a ruddy young lad out of a pastoral existence and sending him to slay a giant in the armor of his best friend’s father whose throne he will one day steal. I should quit before I entertain any more heresy but the good news is this; if God forgives David, who showed evil doers a thing or two about being wicked, then there is hope for the rest of us who rely on the one who led a blameless life on our behalf, Jesus Christ out Lord.
