If God owed us grace, it would no longer be grace. It would simply be justice. Justice is receiving one’s due as a reward or a punishment for certain forms of behavior. Grace, however, is not required. God reserves the right of cosmic executive clemency. It is executive privilege on His part. He can be merciful to whom He wants to be merciful, and He can withhold His mercy or His grace from whomever He decides to withhold it from, for whatever reason He is inclined to do so, in order to accomplish His purposes.
