1 Corinthians 2:12-14

We did not receive the spirit of the world, but we received the Spirit that is from God. We received this Spirit so that we can know all that God has given us. When we speak, we do not use words taught to us by the wisdom that men have. We use words taught to us by the Spirit. We use spiritual words to explain spiritual things. A person who is not spiritual does not accept the gifts that come from the Spirit of God. That person thinks they are foolish. He cannot understand the Spirit’s gifts, because they can only be judged spiritually.
