The Holy Spirit reveals the deep truths of God.
1 Corinthians 2:
6 Yet when I am among mature believers, I do speak with words of wisdom, but not the kind of wisdom that belongs to this world or to the rulers of this world, who are soon forgotten. 7 No, the wisdom we speak of is the mystery of God—his plan that was previously hidden, even though he made it for our ultimate glory before the world began. 8 But the rulers of this world have not understood it; if they had, they would not have crucified our glorious Lord. 9 That is what the Scriptures mean when they say,
“No eye has seen, no ear has heard,
and no mind has imagined
what God has prepared
for those who love him.”
10 But[c] it was to us that God revealed these things by his Spirit. For his Spirit searches out everything and shows us God’s deep secrets. 11 No one can know a person’s thoughts except that person’s own spirit, and no one can know God’s thoughts except God’s own Spirit. 12 And we have received God’s Spirit (not the world’s spirit), so we can know the wonderful things God has freely given us.
