God consents to be pushed out of the world and onto the cross; God is weak and powerless in the world and in precisely this way, and only so, is at our side and helps us. Matt. 8:17 makes it quite clear that Christ helps us not by virtue of his omnipotence but rather by virtue of his weakness and suffering! This is the crucial distinction between Christianity and all religions. Human religiosity directs people in need to the power of God in the world, God as deus ex machina. The Bible directs people toward the powerlessness and the suffering of God; only the suffering God can help.
