1 Corinthians 2:11-13

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.
