Brothers and sisters:
The Spirit scrutinizes everything, even the depths of God.
Among men, who knows what pertains to the man
except his spirit that is within?
Similarly, no one knows what pertains to God except the Spirit of God.
We have not received the spirit of the world
but the Spirit who is from God,
so that we may understand the things freely given us by God.
And we speak about them not with words taught by human wisdom,
but with words taught by the Spirit,
describing spiritual realities in spiritual terms.

Now the natural man does not accept what pertains to the Spirit of God,
for to him it is foolishness, and he cannot understand it,
because it is judged spiritually.
The one who is spiritual, however, can judge everything
but is not subject to judgment by anyone.

For “who has known the mind of the Lord, so as to counsel him?”
But we have the mind of Christ.

Epistle of Paul: First Corinthians
