So much of Psalm 51 is about being cleansed and transformed. This is understandable given the nature of King David’s heinous acts of infidelity and murder. It must have felt like the blood would never leave his hands and that he would be marked with sin forever.
But part of penitence is expressing deep regret, overwhelmed with the guilty sorrow of having done wrong, very wrong, and wanting to do whatever it takes to feel right with God again. So this verse resonates with anyone who has erred in both large and small ways, having laid awake at night thinking about it, weeping in remorse, crying out with contrition.
Lent is the reminder that we have renewal at hand. It is coming. Our hearts will be light again, loving and full of joy.
