(16) For.--This is the proof that the enlightened spiritual man cannot be judged by any one who is not thus enlightened. "Who (thus uninstructed) can know the mind of the Lord Jesus, that he may instruct Him?"

But we.--That is, spiritual men, including the Apostles. The Apostle here identifies Christ with the Spirit, whom he has previously spoken of as the Teacher of spiritual things. He does not mean to assert that the Apostles knew all that the mind of Christ knew, but that all things which they did know were from Him and spiritual (John 15:15).

Verse 16. - Who hath known the mind of the Lord? "The Lord" is Jehovah (see Isaiah 40:13, LXX.; Romans 11:34). This is the reason why no one can judge the spiritual man in his spiritual life. To do so is like judging God. We have the mind of Christ. So Christ himself had told the apostles (John 15:15); and St. Paul always claimed to have been taught by direct revelation from Christ (Galatians 1:11, 12). They had the Spirit of Christ (Romans 8:9), and therefore the mind of Christ.

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.For who hath known the mind of the Lord,.... The deep counsels of his heart, the scheme of salvation by Jesus Christ, as drawn in his eternal mind, the sense of the Spirit of God in the writings of the Old Testament, the things of the Spirit of God, or the doctrines of grace more clearly revealed under the Gospel dispensation; not any natural man, by the light of truth and strength of reason, has known any of these things. The apostle either cites or alludes to Isaiah 40:13

that he may instruct him? not the Lord, who needs no instruction from any, nor can any teach and instruct him, nor would any be so bold and insolent as to attempt it nor does the knowledge of the mind of the Lord qualify any for such a work; since if he knows ever so much of it, he cannot know more than the Lord himself: but the spiritual man, whom a natural man, being ignorant of the mind of the Lord, cannot instruct; and so the words give a very proper and sufficient reason why the spiritual man is not discerned, judged, convinced, and instructed by the natural man:

but we have the mind of Christ; the same with "the mind of the Lord" which proves that Christ is the Lord, or Jehovah, and so truly and properly God; and which is to be understood, not only of the apostles and ministers of the Gospel, but of all true believers; and therefore want no instruction, as they can have none from the natural man; though chiefly of the former, whereby they were abundantly qualified for the further instruction even of spiritual men.
