13 Which things also we speak, not in words which man’s wisdom teaches, but which the Holy Spirit teaches, comparing spiritual things with spiritual things. 14 Now the natural man doesn’t receive the things of God’s Spirit, for they are foolishness to him, and he can’t know them, because they are spiritually discerned. 15 But he who is spiritual discerns all things, and he himself is judged by no one.
Matthew Henry's Commentary on 1 Corinthians 2:13-15
Commentary on 1 Corinthians 2:10-16
(Read 1 Corinthians 2:10-16)
God has revealed true wisdom to us by his Spirit. Here is a proof of the Divine authority of the Holy Scriptures, 2 Peter 1:21. In proof of the Divinity of the Holy Ghost, observe, that he knows all things, and he searches all things, even the deep things of God. No one can know the things of God, but his Holy Spirit, who is one with the Father and the Son, and who makes known Divine mysteries to his church. This is most clear testimony, both to the real Godhead and the distinct person of the Holy Spirit. The apostles were not guided by worldly principles. They had the revelation of these things from the Spirit of God, and the saving impression of them from the same Spirit. These things they declared in plain, simple language, taught by the Holy Spirit, totally different from the affected oratory or enticing words of man's wisdom. The natural man, the wise man of the world, receives not the things of the Spirit of God. The pride of carnal reasoning is really as much opposed to spirituality, as the basest sensuality. The sanctified mind discerns the real beauties of holiness, but the power of discerning and judging about common and natural things is not lost. But the carnal man is a stranger to the principles, and pleasures, and actings of the Divine life. The spiritual man only, is the person to whom God gives the knowledge of his will. How little have any known of the mind of God by natural power! And the apostles were enabled by his Spirit to make known his mind. In the Holy Scriptures, the mind of Christ, and the mind of God in Christ, are fully made known to us. It is the great privilege of Christians, that they have the mind of Christ revealed to them by his Spirit. They experience his sanctifying power in their hearts, and bring forth good fruits in their lives.
