The only Christian theodicy which I find credible is the confession that God does not exempt himself from the horror of human suffering, but is fully baptized into it. God in Christ joins us in a solidarity of suffering, and somehow by his wounds we are healed. Christ saves us from sin and death only by hurling himself into the abyss. The ultimate imitation of Christ is to patiently absorb sin and offer pardon in the name of love. This is grace.
