I Thessalonians 4:8

despiseth, &c.--Greek, "setteth at naught" such engagements imposed on him in his calling, Th1 4:7; in relation to his "brother," Th1 4:6. He who doth so, "sets at naught not man (as for instance his brother), but God" (Psa 51:4) is used of despising or rejecting God's minister, it may mean here, "He who despiseth" or "rejecteth" these our ministerial precepts. who hath also given unto us--So some oldest manuscripts read, but most oldest manuscripts read, "Who (without 'also') giveth (present) unto you" (not "us"). his Spirit--Greek, "His own Spirit, the Holy (One)"; thus emphatically marking "holiness" (Th1 4:7) as the end for which the Holy (One) is being given. "Unto you," in the Greek, implies that the Spirit is being given unto, into (put "into" your hearts), and among you (compare Th1 2:9; Eph 4:30). "Giveth" implies that sanctification is not merely a work once for all accomplished in the past, but a present progressive work. So the Church of England Catechism, "sanctifieth (present) all the elect people of God." "His own" implies that as He gives you that which is essentially identical with Himself, He expects you should become like Himself (Pe1 1:16; Pe2 1:4).

In this chapter the apostle gives earnest exhortations to abound in holiness, with a caution against uncleanness, enforced with several arguments (Th1 4:1-8). He then mentions the great duties of brotherly love, and quietness with industry in our callings (Th1 4:9-12). And concludes with comforting those who mourned for their relations and friends that died in the Lord (Th1 4:13-18).

4:8 Rejecting Paul’s teaching on these matters was the same as rejecting God. • The Holy Spirit empowers Christians to live in accord with God’s will (Ezek 36:27; Rom 8:1-4; Gal 5:16; 1 Jn 3:24).
