Personal integrity is the thing that can bring down the best of us. The easiest thing for us to do is to live one life, and that life would be the life that God gives us. God’s grace is buried when we try to live another life entirely. David’s momentary lust gave way to a double life that included adultery and murder, which forever sullied the greatness that God wanted for him. Sin complicates things in unbelievable ways. Grace gives us the opportunity to live simply and to live fully.
