4:12-19 By patience and fortitude in suffering, by dependence on the promises of God, and keeping to the word the Holy Spirit hath revealed, the Holy Spirit is glorified; but by the contempt and reproaches cast upon believers, he is evil spoken of, and is blasphemed. One would think such cautions as these were needless to Christians. But their enemies falsely charged them with foul crimes. And even the best of men need to be warned against the worst of sins. There is no comfort in sufferings, when we bring them upon ourselves by our own sin and folly. A time of universal calamity was at hand, as foretold by our Saviour, Mt 24:9,10. And if such things befall in this life, how awful will the day of judgment be! It is true that the righteous are scarcely saved; even those who endeavour to walk uprightly in the ways of God. This does not mean that the purpose and performance of God are uncertain, but only the great difficulties and hard encounters in the way; that they go through so many temptations and tribulations, so many fightings without and fears within. Yet all outward difficulties would be as nothing, were it not for lusts and corruptions within. These are the worst clogs and troubles. And if the way of the righteous be so hard, then how hard shall be the end of the ungodly sinner, who walks in sin with delight, and thinks the righteous is a fool for all his pains! The only way to keep the soul well, is, to commit it to God by prayer, and patient perseverance in well-doing. He will overrule all to the final advantage of the believer.

16. a Christian—the name given in contempt first at Antioch. Ac 11:26; 26:28; the only three places where the term occurs. At first believers had no distinctive name, but were called among themselves "brethren," Ac 6:3; "disciples," Ac 6:1; "those of the way," Ac 9:2; "saints," Ro 1:7; by the Jews (who denied that Jesus was the Christ, and so would never originate the name Christian), in contempt, "Nazarenes." At Antioch, where first idolatrous Gentiles (Cornelius, Ac 10:1, 2, was not an idolater, but a proselyte) were converted, and wide missionary work began, they could be no longer looked on as a Jewish sect, and so the Gentiles designated them by the new name "Christians." The rise of the new name marked a new epoch in the Church's life, a new stage of its development, namely, its missions to the Gentiles. The idle and witty people of Antioch, we know from heathen writers, were famous for inventing nicknames. The date of this Epistle must have been when this had become the generally recognized designation among Gentiles (it is never applied by Christians to each other, as it was in after ages—an undesigned proof that the New Testament was composed when it professes), and when the name exposed one to reproach and suffering, though not seemingly as yet to systematic persecution.

let him not be ashamed—though the world is ashamed of shame. To suffer for one's own faults is no honor (1Pe 4:15; 1Pe 2:20),—for Christ, is no shame (1Pe 4:14; 1Pe 3:13).

but let him glorify God—not merely glory in persecution; Peter might have said as the contrast, "but let him esteem it an honor to himself"; but the honor is to be given to God, who counts him worthy of such an honor, involving exemption from the coming judgments on the ungodly.

on this behalf—The oldest manuscripts and Vulgate read, "in this name," that is, in respect of suffering for such a name.
