1 Corinthians 2:11-13

After all, who can really see into a person’s heart and know his hidden impulses except for that person’s spirit? So it is with God. His thoughts and secrets are only fully understood by his Spirit, the Spirit of God. For we did not receive the spirit of this world system but the Spirit of God, so that we might come to understand and experience all that grace has lavished upon us. And we articulate these realities with the words imparted to us by the Spirit and not with the words taught by human wisdom. We join together Spirit-revealed truths with Spirit-revealed words.
