1 Thessalonians 4:7

Ver. 7,8. These two verses are added, as further arguments to persuade to that chastity he had spoken of, called sanctification, 1 Thessalonians 4:3,4. The first is taken from their Christian calling, which is not to uncleanness, but to chastity, called holiness. When they were Gentiles in state, they lived in the lust of uncleanness, but they were now called by the power of the gospel, and brought to such a profession that did forbid and condemn it. And the author of their call is God himself, though the apostles and other ministers were the instruments. Whence he fetcheth this second argument, 1 Thessalonians 4:8, that if this chastity he despised, or rejected, as we may read the text, it is not man, but God, that is despised. To despise a minister in a commandment he delivers from God is to despise God himself, Luke 10:16, &c.; and the apostle doth here intimate, not to obey the commandment of God is a despising God. Or, that the apostle was despised by some because of the outward meanness of his person, or questioning his authority. Who hath also given unto us his holy Spirit: this he adds as a third argument; so that what he had preached to them, was not from himself, but from the Holy Spirit. Or if by us he means these Thessalonians also, as some copies read it, he hath given you, &c., then he argues from the gift of the Holy Spirit they had received against living in the sin of uncleanness. This would be very disagreeable, not only to their holy calling, but the Holy Spirit God had given them. Or else these arguments of the apostle are to persuade to universal holiness, taking sanctification and holiness in a larger sense; and uncleanness, for all sin in general standing opposite thereunto. Sin is often spoken of in Scripture under the notion of filth, defilement, pollution, &c., and so was typed forth under the law; and to be cleansed from sin is a cleansing man from filthiness, 2 Corinthians 7:1; so that to live in sin, as the apostle argues, is to live in uncleanness, to contradict our holy calling, to despise God, and to walk contrary to the nature and dictates of his Holy Spirit.
