1 Corinthians 2:11 in the World English Bible
For who among men knows the things of a man except the spirit of the man which is in him? Even so, no one knows the things of God except God’s Spirit.
Context
10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
11 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.
12 Now 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.
