Jurgen Moltmann writes:
Even more important, however, is the recognition that if Jesus were not “God’s son,” if God were not “in him,” then his suffering would have no divine meaning for the redemption of the world. It would disappear into the endless history of the suffering of murdered people. But, if “one of the trinity suffers,” then healing can come to wounded humanity and hope can enter a dying world.
