Christians face an interesting theological challenge regarding the crucifixion of Jesus, insofar as we want to know why Jesus had to suffer in order to save the faithful. God, being omnipotent, appears to have the power to save the faithful, regardless of whether he also sent Jesus to suffer on the cross. In order to explain why it was better for him to do so, we might be tempted to invoke the notion of justice. However, if we want to appeal to God's favorite system of justice to explain why Jesus had to suffer, then we must know why that system is ultimately good for us. Since we do not in fact know how God's rules of cosmic justice are ultimately good for us, then no appeal to those rules will serve as a satisfactory explanation.
