1 Corinthians 2:6-9, 9, 9-16, 16

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. 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. But the rulers of this world have not understood it; if they had, they would not have crucified our glorious Lord. 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.”

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.”

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.” But 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. 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. And we have received God’s Spirit (not the world’s spirit), so we can know the wonderful things God has freely given us. When we tell you these things, we do not use words that come from human wisdom. Instead, we speak words given to us by the Spirit, using the Spirit’s words to explain spiritual truths. But people who aren’t spiritual can’t receive these truths from God’s Spirit. It all sounds foolish to them and they can’t understand it, for only those who are spiritual can understand what the Spirit means. Those who are spiritual can evaluate all things, but they themselves cannot be evaluated by others. For

For, “Who can know the LORD’s thoughts? Who knows enough to teach him?” But we understand these things, for we have the mind of Christ.
