“A man who is unspiritual refuses what belongs to the Spirit of God; it is folly to him; he cannot grasp it, because it needs to be judged in the light of the Spirit.”
Paul is essentially telling us that without the Spirit of God, it is impossible for man — who is born in a fallen, unspiritual state — to grasp “what belongs to the Spirit of God.” The things of God are “folly” to man; “he cannot grasp [them.]” Man does not and cannot seek God, or comprehend God’s wisdom or purposes.
On the other hand,”a man gifted with the Spirit can judge the worth of everything.” (1 Corinthians 2: 15) Because we are gifted with the Spirit of God, Paul says, “we possess the mind of Christ.” (1 Corinthians 2: 16)
And, with the mind of Christ, we understand that “divine folly is wiser than the wisdom of man, and divine weakness stronger than man’s strength.” (1 Corinthians 1: 25) Paul says, “I speak God’s hidden wisdom, His secret purpose framed from the very beginning to bring us to our full glory. The powers that rule the world do not know it; if they did, they would not have crucified the Lord of glory. But, in the words of Scripture, ‘Things beyond our seeing, things beyond our hearing, things beyond our imagining, all prepared by God for those who love Him’, these it is that God reveals to us through His Spirit.” (1 Corinthians 2: 7 – 10)
