An excerpt from "BibleRef.com" entitled, "What does 1 Corinthians 2:14 mean?" states: "The natural person rejects as foolish anything that comes from the Spirit of God. Those who have only their human senses and human reason will never be able to comprehend the spiritual truths of God's revelation about sin, salvation, and Christ to His people. It's unreasonable to expect non-believers to process spiritual issues in the same way as believers. It's impossible to expect them to have the "mind of Christ" (1 Corinthians 2:16) when they don't have the Spirit of God."
