5:9-15 The apostle quickens himself and others to acts of duty. Well-grounded hopes of heaven will not encourage sloth and sinful security. Let all consider the judgment to come, which is called, The terror of the Lord. Knowing what terrible vengeance the Lord would execute upon the workers of iniquity, the apostle and his brethren used every argument and persuasion, to lead men to believe in the Lord Jesus, and to act as his disciples. Their zeal and diligence were for the glory of God and the good of the church. Christ's love to us will have a like effect upon us, if duly considered and rightly judged. All were lost and undone, dead and ruined, slaves to sin, having no power to deliver themselves, and must have remained thus miserable for ever, if Christ had not died. We should not make ourselves, but Christ, the end of our living and actions. A Christian's life should be devoted to Christ. Alas, how many show the worthlessness of their professed faith and love, by living to themselves and to the world!
10. appear—rather, "be made manifest," namely, in our true character. So "appear," Greek, "be manifested" (Col 3:4; compare 1Co 4:5). We are at all times, even now, manifest to God; then we shall be so to the assembled intelligent universe and to ourselves: for the judgment shall be not only in order to assign the everlasting portion to each, but to vindicate God's righteousness, so that it shall be manifest to all His creatures, and even to the conscience of the sinner himself.
receive—His reward of grace proportioned to "the things done," &c. (2Co 9:6-9; 2Jo 8). Though salvation be of grace purely, independent of works, the saved may have a greater or less reward, according as he lives to, and labors for, Christ more or less. Hence there is scope for the holy "ambition" (see on 2Co 5:9; Heb 6:10). This verse guards against the Corinthians supposing that all share in the house "from heaven" (2Co 5:1, 2). There shall be a searching judgment which shall sever the bad from the good, according to their respective,deeds, the motive of the deeds being taken into account, not the mere external act; faith and love to God are the sole motives recognized by God as sound and good (Mt 12:36, 37; 25:35-45),
done in his body—The Greek may be, "by the instrumentality of the body"; but English Version is legitimate (compare Greek, Ro 2:27). Justice requires that substantially the same body which has been the instrument of the unbelievers' sin, should be the object of punishment. A proof of the essential identity of the natural and the resurrection body.
