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, 2Pe 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.
13. also—We not only know by the Holy Ghost, but we also speak the "things freely given to us of God" (1Co 2:12).
which the Holy Ghost teacheth—The old manuscripts read "the Spirit" simply, without "Holy."
comparing spiritual things with spiritual—expounding the Spirit-inspired Old Testament Scripture, by comparison with the Gospel which Jesus by the same Spirit revealed [Grotius]; and conversely illustrating the Gospel mysteries by comparing them with the Old Testament types [Chrysostom]. So the Greek word is translated, "comparing" (2Co 10:12). Wahl (Key of the New Testament) translates, "explaining (as the Greek is translated, Ge 40:8, the Septuagint) to spiritual (that is, Spirit-taught) men, spiritual things (the things which we ourselves are taught by the Spirit)." Spirit-taught men alone can comprehend spiritual truths. This accords with 1Co 2:6, 9, 10, 14, 15; 1Co 3:1. Alford translates, "Putting together (combining) spirituals with spirituals"; that is, attaching spiritual words to spiritual things, which we should not do, if we were to use words of worldly wisdom to expound spiritual things (so 1Co 2:1, 4; 1Pe 4:11). Perhaps the generality of the neuters is designed to comprehend these several notions by implication. Comparing, or combining, spirituals with spirituals; implying both that spiritual things are only suited to spiritual persons (so "things" comprehended persons, 1Co 1:27), and also that spiritual truths can only be combined with spiritual (not worldly-wise) words; and lastly, spirituals of the Old and New Testaments can only be understood by mutual comparison or combination, not by combination with worldly "wisdom," or natural perceptions (1Co 1:21, 22; 2:1, 4-9; compare Ps 119:18).
