For God hath not called us. This appears to be the same sentiment with the preceding one -- that the will of God is our sanctification. There is, however, a little difference between them. For after having discoursed as to the correcting of the vices of the flesh, he proves, from the end of our calling, that God desires this. For he sets us apart to himself as his peculiar possession. [1] Again, that God calls us to holiness, he proves by contraries, because he rescues us, and calls us back, from unchastity. From this he concludes, that all that reject this doctrine reject not men, but God, the Author of this calling, which altogether falls to the ground so soon as this principle as to newness of life is overthrown. Now, the reason why he rouses himself so vehemently is, because there are always wanton persons who, while they fearlessly despise God, treat with ridicule all threatenings of his judgment, and at the same time hold in derision all injunctions as to a holy and pious life. Such persons must not be taught, but must be beaten with severe reproofs as with the stroke of a hammer.

Footnotes

1 - "Comme pour son propre heritage et particulier;" -- "As for his peculiar and special inheritance."

For God hath not called us unto uncleanness - When he called us to be his followers, it was not that we should lead lives of impurity, but of holiness. We should, therefore, fulfil the purposes for which we were called into his kingdom. The word "uncleanness" (ἀκαθαρσία akatharsia), means, properly, "impurity, filth;" and then, in a moral sense, "pollution, lewdness," as opposed to chastity; Romans 1:24; Romans 6:19; 2-Corinthians 12:21; Galatians 5:19; Ephesians 4:19; Ephesians 5:3; Colossians 3:5.

God hath not called us unto uncleanness - He is the creator of male and female, and the institutor of marriage, and he has called men and women to this state; but the end of this and all the other callings of God to man is holiness, not uncleanness. And they who use the marriage state as he directs, will find it conducive to their holiness and perfection.

For God hath not called us,.... The Syriac version reads "you". This is another reason to enforce the above exhortations, and to caution them against the above unclean practices, taken from the end of the effectual calling by the efficacious grace of God, which is not
unto uncleanness of any sort, as before specified. This they had lived in before their calling, and were now called from it into communion with Christ, who loves righteousness, and hates iniquity; and by the Gospel, which teaches to deny ungodliness, and worldly lusts, and to forsake all impurity, both of flesh and spirit:
but this call is
unto holiness of life and conversation in general, and to chastity in thought, look, word, and actions in particular; for God that calls is holy, and therefore those who are called ought to be so; the calling with which they are called is an holy calling, principles of grace and holiness are wrought in their souls, when they are called; and the end of their calling is to live soberly, righteously, and godly; and then, and then only, do they walk worthy of that calling wherewith they are called, and of God who has, by his grace, called them to his kingdom and glory.

unto uncleanness--Greek, "for the purpose of."
unto--rather as Greek, "in"; marking that "holiness" is the element in which our calling has place; in a sphere of holiness. Saint is another name for Christian.
