The perfect surrender and humiliation were undergone by Christ: perfect because He was God, surrender and humiliation because He was man. Now the Christian belief is that if we somehow share the humility and suffering of Christ we shall also share in His conquest of death and find a new life after we have died and in it become perfect, and perfectly happy, creatures. This means something much more than our trying to follow his teaching. People often ask when the next step in evolution—the step to something beyond man—will happen. But in the Christian view, it has happened already. In Christ a new kind of man appeared: and the new kind of life which began in Him is to be put into us.
