The power and attraction Jesus Christ exercises over men never comes from him alone, but from him as Son of the Father. It comes from him in his Sonship in a double way, as man living to God and as God living with men. Belief in him and loyalty to his cause involve men in the double movement, from world to God and from God to world. Even when theologies fail to do justice to this fact, Christians living with Christ in their cultures are aware of it. For they are forever being challenged to abandon all things for the sake of God; and forever being sent back into the world to teach and practice all the things that have been commanded them.
