6Yet 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.
7No, 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.
9That 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.”
13When 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.
14But 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.
