The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit.

What does this mean

This statement is from the Bible (1 Corinthians 2:14) and it is expressing the idea that a person who lacks a connection with the Holy Spirit, or a spiritual understanding, will not be able to accept or comprehend spiritual matters. They may see spiritual teachings or concepts as foolish or irrational because they can only be understood through the guidance of the Spirit. In essence, it suggests that a spiritual approach is necessary to fully appreciate and comprehend the deeper truths and mysteries of faith.
