1:6-10 When careless, ignorant, and immoral persons are turned from their carnal pursuits and connexions, to believe in and obey the Lord Jesus, to live soberly, righteously, and godly, the matter speaks for itself. The believers under the Old Testament waited for the coming of the Messiah, and believers now wait for his second coming. He is yet to come. And God had raised him from the dead, which is a full assurance unto all men that he will come to judgment. He came to purchase salvation, and will, when he comes again, bring salvation with him, full and final deliverance from that wrath which is yet to come. Let all, without delay, flee from the wrath to come, and seek refuge in Christ and his salvation.
10. This verse distinguishes them from the Jews, as 1Th 1:9 from the idolatrous Gentiles. To wait for the Lord's coming is a sure characteristic of a true believer, and was prominent amidst the graces of the Thessalonians (1Co 1:7, 8). His coming is seldom called his return (Joh 14:3); because the two advents are regarded as different phases of the same coming; and the second coming shall have features altogether new connected with it, so that it will not be a mere repetition of the first, or a mere coming back again.
his Son … raised from the dead—the grand proof of His divine Sonship (Ro 1:4).
delivered—rather as Greek, "who delivereth us." Christ has once for all redeemed us; He is our Deliverer ALWAYS.
wrath to come—(1Th 5:9; Col 3:6).
