Answer: “‘The wisdom of God in a mystery’ is all that is unveiled of God’s counsels in Christ; everything that God has done in Christ.” And this hidden wisdom can only be received by the spiritual mind. Those who are perfect here, are those who can take in what the apostle had to communicate. The Corinthians were full of the wisdom of the world; they had to learn that the cross of Christ set all that aside. Christ and Him crucified he set before them. He tells them these things are revealed by the Holy Spirit, (verse 10), and received and known by the Spirit, (verse 12), and communicated by spiritual means, (see New Trans. verse 13), and not in words which man’s wisdom teacheth, but which the Holy Spirit teacheth. “The mind of Christ,” (verse 16), is the qualification each believer has to receive what God teaches.
