The New John Gill Exposition of the Entire Bible1 Corinthians 2:11
For what man knoweth the things of a man…
of a man's heart, the conceptions of his mind, the schemes he is
drawing there, his designs, purposes, and intentions; these can
never be known by another man, no, nor by angels or devils; not by
any creature; by none
save the spirit of a man which is in him?
which is only conscious
to, and can only make known the things that are in him:
even so the things of God knoweth no man, but the Spirit of God;
which, as it proves how secret, hidden, unknown, the mysteries of
grace are, until revealed by the Spirit; so it gives full evidence
to the deity of the Holy Ghost, and clearly shows he must be God,
who is in him, knows the thoughts of his heart, the counsels of his
mind, his purposes and decrees, and what is contained in them.
