1 Corinthians 2:10-13

10But unto us God revealed them through the Spirit: for the Spirit searcheth all things, yea, the deep things of God. 11For who among men knoweth the things of a man, save the spirit of the man, which is in him? even so the things of God none knoweth, save the Spirit of God. 12But we received, not the spirit of the world, but the spirit which is from God; that we might know the things that were freely given to us of God. 13Which things also we speak, not in words which man’s wisdom teacheth, but which the Spirit teacheth; combining spiritual things with spiritual words.
