For when in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.

For I determined not to know any thing among you, save Jesus Christ, and him crucified.

For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.

For how knowest thou, O wife, whether thou shalt save thy husband? or how knowest thou, O man, whether thou shalt save thy wife?

To the weak I became as weak, that I might gain the weak: I have become all things to all men, that I might by all means save some.
