One and the same spirit distributing. Hence it follows that those act amiss who, having no concern as to participation, break asunder that holy harmony, that is fitly adjusted in all its parts, only when under the guidance of the same Spirit, all conspire toward one and the same object. He again calls the Corinthians to unity, by reminding them that all have derived from one fountain whatever they possess, while he instructs them, at the same time, that no one has so much as to have enough within himself, so as not to require help from others. For this is what he means by these words -- distributing to every one severally as he willeth The Spirit of God, therefore, distributes them among us, in order that we may make all contribute to the common advantage. To no one does he give all, lest any one, satisfied with his particular portion, should separate himself from others, and live solely for himself. The same idea is intended in the adverb severally, as it is of great importance to understand accurately that diversity by which God unites us mutually to one another. [1] Now, when will is ascribed to the Spirit, and that, too, in connection with power, we may conclude from this, that the Spirit is truly and properly God.

Footnotes

1 - "Par laquelle Dieu nou conioint et oblige mutuellement les uns aux autres;" -- "By which God connects and binds us mutually to one another."

But all these - All these various endowments.
Worketh - Produces. All these are to be traced to him.
That one and the self-same Spirit - The Holy Spirit, Acts 2. They were all, though so different in themselves, to be traced to the Holy Spirit, just as all the natural endowments of people - their strength, memory, judgment, etc. - though so various in themselves are to be traced to the same God.
Dividing to every man severally - Conferring on each one as he pleases. He confers on each one that which he sees to be best, and most wise, and proper.
As he will - As he chooses or as in his view seems best. Dr. Doddridge remarks, that this word does "not so much express arbitrary pleasure, as a determination founded on "wise" counsel." It implies, however, that he does it as a sovereign; as he sees to be right and best. He distributes these favors as to him seems best adapted to promote the welfare of the whole church and to advance his cause. Some of the doctrines which are taught by this verse are the following:
(1) The Holy Spirit is a "person." For, he acts as a person; distributes favors, confers endowments and special mercies "as he will." This proves that he is, in some respects, distinguished from the Father and the Son. It would be absurd to say of an "attribute" of God, that it confers favors, and distributes the various endowments of speaking with tongues, and raising the dead. And if so, then the Holy Spirit is "not" an attribute of God.
(2) he is a sovereign. He gives to all as he pleases. In regard to spiritual endowments of the highest order, he deals with people as he does in the common endowments bestowed upon people, and as he does in temporal blessings. He does not bestow the same blessings on all, nor make all alike. He dispenses his favors by a rule which he has not made known, but which, we may be assured, is in accordance with wisdom and goodness. He wrongs no one; and he gives to all the favors which might be connected with eternal life.
(3) no man should be proud of his endowments. Whatever they may be, they are the gifts of God, bestowed by his sovereign will and mercy. But assuredly we should not be proud of that which is the mere "gift" of another, and which has been bestowed, not in consequence of any merit of ours, but according to his mere sovereign will.
(4) no man should be depressed, or should despise his own gifts, however humble they may be. In their own place, they may be as important as the higher endowments of others. That God has placed him where he is, or has given less splendid endowments than he has to others, is no fault of his. There is no crime in it; and he should, therefore, strive to improve his "one talent," and to make himself useful in the rank where he is placed. And,
(5) No man should despise another because be is in a more bumble rank, or is less favored than himself. God has made the difference, and we should respect and honor his arrangements, and should show that "respect" and "honor" by regarding with kindness, and treating as fellow laborers with us, all who occupy a more humble rank than we do.

But all these worketh that one and the self-same Spirit - All these gifts are miraculously bestowed; they cannot be acquitted by human art or industry, the different languages excepted; but they were given in such a way, and in such circumstances, as sufficiently proved that they also were miraculous gifts.

But all these worketh that one and the selfsame Spirit, dividing to every man severally (6) as he will.
(6) He adds moreover somewhat else, that is, that although these gifts are unequal, yet they are most wisely divided, because the will of the Spirit of God is the rule of this distribution.

But all these worketh that one and the selfsame Spirit,.... Though these gifts, ministrations, and operations, are so different in themselves, and are bestowed upon different persons, yet they are all wrought by one and the same Spirit of God, who is the true Jehovah, and properly God, as these his works declare; for who, but the most high God, could ever communicate such gifts to men?
Dividing to every man severally as he will; giving one man this gift, and another that; imparting such a measure to one, and such a portion to another, just as seems good in his sight. For as his special grace in regeneration is dispensed when and where, and to whom he pleases, signified by the blowing of the wind where it listeth, John 3:8 so his gifts, ordinary and extraordinary, are severally distributed, according to his sovereign will and pleasure. This is a clear and full proof of the personality of the Spirit, who is not only distinguished from his gifts, and the distribution of them, which is a personal act described to him; but this is said to be done according to his will, which supposes him an intelligent agent, capable of choosing and willing; and whose will agrees with the Father's, and with the Son's.

as he will-- (1-Corinthians 12:18; Hebrews 2:4).

As he willeth - The Greek word does not so much imply arbitrary pleasure, as a determination founded on wise counsel.
