1 Corinthians 2:10-11

New King James Version

¹⁰ But ^(A)God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. ¹¹ For what man knows the things of a man except the ^(B)spirit of the man which is in him? ^(C)Even so no one knows the things of God except the Spirit of God.
