7But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory: 8Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory. 9But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. 10But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.11For 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. 12Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. 13Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
