But God hath revealed them to us. Having shut up all mankind in blindness, and having taken away from the human intellect the power of attaining to a knowledge of God by its own resources, he now shows in what way believers are exempted from this blindness, -- by the Lord's honoring them with a special illumination of the Spirit. Hence the greater the bluntness of the human intellect for understanding the mysteries of God, and the greater the uncertainty under which it labors, so much the surer is our faith, which rests for its support on the revelation of God's Spirit. In this, too, we recognize the unbounded goodness of God, who makes our defect contribute to our advantage. For the Spirit searcheth all things This is added for the consolation of the pious, that they may rest more securely in the revelation which they have from the Spirit of God, as though he had said. "Let it suffice us to have the Spirit of God as a witness, for there is nothing in God that is too profound for him to reach." For such is the import here of the word searcheth By the deep things you must understand -- not secret judgments, which we are forbidden to search into, but the entire doctrine of salvation, which would have been to no purpose set before us in the Scriptures, were it not that God elevates our minds to it by his Spirit.

But God hath revealed them - That is, those elevated views and enjoyments to which people everywhere else had been strangers, and which have been under all other forms of religion unknown, have been communicated to us by the revelation of God - This verse commences the "third" part of this chapter, in which the apostle shows how these truths, so full of wisdom had been communicated to Christians. It had not been by any native endowments of theirs; not by any strength of faculties, or powers. but solely by revelation from God.Unto us - That is, first to the apostles; secondly, to all Christians - to the church and the world through their inspired instructors; and third, to all Christians by the illuminating agency of the Spirit on their hearts. The connection shows that he did not mean to confine this declaration to the apostles merely, for his design was to show that all Christians had this knowledge of the true wisdom. It was true that this was revealed in an eminent manner to the apostles, and through their inspired preaching and writings; but it is also true, that the same truths are communicated by the agency of the same Spirit to all Christians; John 16:12-14. No truth is now communicated to Christians which was not revealed to and by the inspired writers; but the same truths are imparted by means of their writings, and by the illumination of the Spirit to all the true friends of God.
By his Spirit - By the Holy Spirit, that was promised by the Saviour. John 14:26; John 15:26-27; John 16:7-14. This proves:
(1) That people by nature are not able to discover the deep things of God - the truths which are needful to salvation.
(2) that the apostles were inspired by the Holy Spirit; and if so, then the Scriptures are inspired.
(3) that all Christians are the subjects of the teaching of the Holy Spirit; that these truths are made known to them by his illumination; and that but for this, they would remain in the same darkness as other men.
For the Spirit - The Holy Spirit, or the Spirit of God; see 1-Corinthians 2:11.
Searcheth - This word does not fully express the force of the original ἐρευνᾷ ereuna. It means to search accurately, diligently, so as fully to understand; such profound research as to have thorough knowledge. So David uses the Hebrew word חקר chaaqar in Psalm 139:1. So the word is used to denote a careful and accurate investigation of secret and obscure things, in 1-Peter 1:11. Compare John 7:52; Romans 8:27; Revelation 2:23, where it is used to denote that profound and accurate search by which the desires and feelings of the heart are known - implying the most profound knowledge of which we can have any conception; see Proverbs 20:27. Here it means, that the Holy Spirit has an intimate knowledge of all things. It is not to be supposed that he searches, or inquires as people do who are ignorant; but that he has an intimate and profound knowledge, such as is usually the result of a close and accurate search. The result is what the apostle means to state - the accurate, profound, and thorough knowledge, such as usually attends research. He does not state the mode in which it is obtained; but the fact. And he uses a word more emphatic than simple knowledge, because he designs to indicate that his knowledge is profound, entire, and thorough.
All things - All subjects; all laws; all events; all beings.
The deep things of God - He has a thorough knowledge of the hidden counsels or purposes of God; of all his plans and purposes. He sees all his designs. He sees all his councils; all his purposes in regard to the government of the universe, and the scheme of salvation. He knows all whom God designs to save; he sees all that they need; and he sees how the plan of God is suited to their salvation - This passage proves:
(1) That the Spirit is, in some respects, distinct from the Father, or from him who is here called God. Else how could he be said to search all things, even the deep purposes of God? To "search" implies "action, thought, personality." An attribute of God cannot be said to search. How could it be said of the justice, the goodness, the power, or the wisdom of God that it "searches," or "acts?" To search, is the action of an intelligent agent, and cannot be performed by an attribute.
(2) the Spirit is omniscient. He searches or clearly understands "all things" - the very definition of omniscience. He understands all the profound plans and counsels of God. And how can there be a higher demonstration of omniscience than to "know God?" - But if omniscient, the Holy Spirit is divine - for this is one of the incommunicable attributes of God; 1-Chronicles 28:9; Psalm 139:1; Jeremiah 17:10.
(3) he is not a distinct being from God. There is a union between him and God, such as may be compared to the union between a man and his soul, 1-Corinthians 2:11. God is one; and though he subsists as Father, Son, and Spirit, yet he is one God, Deuteronomy 6:4 - This passage is, therefore, a very important, and a decisive one in regard to the personality and divinity of the Holy Spirit.

But God hath revealed them unto us - A manifest proof that the apostle speaks here of the glories of the Gospel, and not of the glories of the future world.
For the Spirit searcheth all things - This is the Spirit of God, which spoke by the prophets, and has now given to the apostles the fullness of that heavenly truth, of which He gave to the former only the outlines.
Yea, the deep things of God - It is only the Spirit of God which can reveal the counsels of God: these are the purposes which have existed in His infinite wisdom and goodness from eternity; and particularly what refers to creation, providence, redemption, and eternal glory, as far as men and angels are concerned in these purposes. The apostles were so fully convinced that the scheme of redemption proclaimed by the Gospel was Divine, that they boldly asserted that these things infinitely surpassed the wisdom and comprehension of man. God was now in a certain way become manifest; many attributes of his, which to the heathen world would have for ever lain in obscurity, (for the world by wisdom knew not God), were now not only brought to light as existing in him, but illustrated by the gracious displays which He had made of himself. It was the Spirit of God alone that could reveal these things; and it was the energy of that Spirit alone that could bring them all into effect - stamp and seal them as attributes and works of God for ever. The apostles were as truly conscious of their own inspiration as they were that they had consciousness at all; and what they spoke, they spoke as they were moved by the Holy Ghost.

(9) But God hath revealed [them] unto us by his Spirit: for the Spirit (k) searcheth all things, yea, the deep things of God.
(9) A question: if it surpasses the capacity of men, how can it be understood by any man, or how can you declare and preach it? By a special enlightening of God's Spirit, with which whoever is inspired, he can enter even into the very secrets of God.
(k) There is nothing so secret and hidden in God, but the Spirit of God penetrates it.

But God hath revealed them unto us,.... Should it be said, that since this wisdom is so hidden and mysterious, the doctrines of the Gospel are so unknown, so much out of the sight and understanding of men, how come any to be acquainted with them? The answer is ready, God has made a revelation of them, not only in his word, which is common to men, nor only to his ministers, but to private Christians and believers,
by his Spirit; which designs not the external revelation made in the Scriptures, though that also is by the Spirit; but the internal revelation and application of the truths of the Gospel to the souls of men, which is sometimes ascribed to the Father of Christ. Matthew 16:17 sometimes to Christ himself, Galatians 1:12 and sometimes to the Spirit of Christ, Ephesians 1:17 and who guides into all truth, John 16:13, and here to the Father by the Spirit:
for the Spirit searcheth all things, yea, the deep things of God; which does not suppose any ignorance of these things in the Spirit, antecedent to his searching of them; but his complete and perfect knowledge of them; even as God's searching of the hearts of men expresses his omniscience, and through knowledge of all that is in them: the "all things" the Spirit searches into, and has a perfect knowledge of, do not design in the utmost extent everything which comes within the compass of his infinite understanding; but every thing that is in, or belongs to the Gospel of Christ, even the more mysterious and sublime, as well as the more plain and easy doctrines: for the "deep things of God" intend not the perfections of his nature, which are past finding out unto perfection by men; nor the depths of his wise and righteous providence; but the mysterious doctrines of the Gospel, the fellowship of the mystery which was hid in God, his wise counsels of old concerning man's salvation, the scheme of things drawn in his eternal mind, and revealed in the word.

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.

revealed . . . by . . . Spirit--The inspiration of thoughts (so far as truth essential to salvation is concerned) makes the Christian (1-Corinthians 3:16; 1-Corinthians 12:3; Matthew 16:17; John 16:13; 1-John 2:20, 1-John 2:27); that of words, the PROPHET (2-Samuel 23:1-2; 1-Kings 13:1, 1-Kings 13:5), "by the word of the Lord" (1-Corinthians 2:13; John 20:30-31; 2-Peter 1:21). The secrets of revelation are secret to some, not because those who know them will not reveal them (for indeed, the very notion of revelation implies an unveiling of what had been veiled), but because those to whom they are announced have not the will or power to comprehend them. Hence the Spirit-taught alone know these secrets (Psalm 25:14; Proverbs 3:32; John 7:17; John 15:15).
unto us--the "perfect" or fully matured in Christian experience (1-Corinthians 2:6). Intelligent men may understand the outline of doctrines; but without the Holy Spirit's revelation to the heart, these will be to them a mere outline--a skeleton, correct perhaps, but wanting life [WHATLEY, Cautions for the Times, 14], (Luke 10:21).
the Spirit searcheth--working in us and with our spirits (compare Romans 8:16, Romans 8:26-27). The Old Testament shows us God (the Father) for us. The Gospels, God (the Son) with us. The Acts and Epistles, God (the Holy Ghost) in us [MONOD], (Galatians 3:14).
deep things of God-- (Psalm 92:5). His divine nature, attributes, and counsels. The Spirit delights to explore the infinite depths of His own divine mind, and then reveal them to us, according as we are capable of understanding them (Deuteronomy 29:29). This proves the personality and Godhead of the Holy Ghost. Godhead cannot be separated from the Spirit of God, as manhood cannot be separated from the Spirit of man [BENGEL].

But God hath revealed them unto us by his Spirit. These wonders of the love of God, not seen by eye, nor heard by ear, nor revealed to the senses, were revealed by the Spirit to the apostles (to us), and made known through them to full-grown Christians ("the perfect," 1-Corinthians 2:6).
The Spirit searcheth, etc. The Holy Spirit, imparted so freely to the apostles to lead them into all truth (John 16:13), is the Spirit of God. Hence this Spirit imparts a knowledge of the deep things of God. The secrets of the divine wisdom are thus made known.
For what man knoweth, etc. A man's spirit knows all his secrets, though these are unknown to another man. So God's Spirit knows the Divine secrets, and imparts these wherever he dwells in full measure as the Spirit of knowledge.
Now we have received, etc. We apostles. The Spirit received by all the apostles was not the spirit of the world, but the Holy Spirit which Christ promised them as a guide into all truth. Hence they were enabled to know what God imparted freely to them.
Which things we also speak. The grand truths, "the hidden wisdom," "the mystery of God," revealed to them through the Spirit, they spoke to others. These things they spoke, not in the words of man's wisdom, not in the garb of philosophy, but in the words given by the Holy Spirit.
Comparing spiritual things with spiritual. This difficult clause has received many explanations. Canon Cook explains it: "Matching spiritual things with spiritual words." Conybeare and Howson say: "Explaining spiritual things to spiritual men." This last view, which Canon Cook says does no violence to the Greek, harmonizes best with 1-Corinthians 2:6 and 1-Corinthians 2:14. I think that 1-Corinthians 2:14, the next verse, shows that this is the true meaning.

But God hath revealed - Yea, and "freely given," 1-Corinthians 2:12. Them to us - Even inconceivable peace, and joy unspeakable. By his Spirit - Who intimately and fully knows them. For the Spirit searcheth even the deep things of God - Be they ever so hidden and mysterious; the depths both of his nature and his kingdom.
