The apostle makes an apology for his manner of preaching, Co1 2:1. And gives the reason why he adopted that manner, Co1 2:2-5. He shows that this preaching, notwithstanding it was not with excellence of human speech or wisdom, yet was the mysterious wisdom of God, which the princes of this world did not know, and which the Spirit of God alone could reveal, Co1 2:6-10. It is the Spirit of God only that can reveal the things of God, Co1 2:11. The apostles of Christ know the things of God by the Spirit of God, and teach them, not in the words of man's wisdom, but in the words of that Spirit, Co1 2:12, Co1 2:13. The natural man cannot discern the things of the Spirit, Co1 2:14. But the spiritual man can discern and teach them, because he has the mind of Christ, Co1 2:15, Co1 2:16.
