Ephesians 6:11
11. the whole armour—the armor of light (Ro 13:12); on the right hand and left (2Co 6:7). The panoply offensive and defensive. An image readily suggested by the Roman armory, Paul being now in Rome. Repeated emphatically, Eph 6:13. In Ro 13:14 it is, "Put ye on the Lord Jesus Christ"; in putting on Him, and the new man in Him, we put on "the whole armor of God." No opening at the head, the feet, the heart, the belly, the eye, the ear, or the tongue, is to be given to Satan. Believers have once for all overcome him; but on the ground of this fundamental victory gained over him, they are ever again to fight against and overcome him, even as they who once die with Christ have continually to mortify their members upon earth (Ro 6:2-14; Col 3:3, 5).
of God—furnished by God; not our own, else it would not stand (Ps 35:1-3). Spiritual, therefore, and mighty through God, not carnal (2Co 10:4). wiles—literally, "schemes sought out" for deceiving (compare 2Co 11:14). the devil—the ruling chief of the foes (Eph 6:12) organized into a kingdom of darkness (Mt 12:26), opposed to the kingdom of light. Ephesians 6:14
14. Stand—The repetition in Eph 6:11, 14, shows that standing, that is, maintaining our ground, not yielding or fleeing, is the grand aim of the Christian soldier. Translate as Greek, "Having girt about your loins with truth," that is, with truthfulness, sincerity, a good conscience (2Co 1:12; 1Ti 1:5, 18; 3:9). Truth is the band that girds up and keeps together the flowing robes, so as that the Christian soldier may be unencumbered for action. So the Passover was eaten with the loins girt, and the shoes on the feet (Ex 12:11; compare Isa 5:27; Lu 12:35). Faithfulness (Septuagint, "truth") is the girdle of Messiah (Isa 11:5): so truth of His followers.
having on—Greek, "having put on." breastplate of righteousness— (Isa 59:17), similarly of Messiah. "Righteousness" is here joined with "truth," as in Eph 5:9: righteousness in works, truth in words [ESTIUS] (1Jo 3:7). Christ's righteousness inwrought in us by the Spirit. "Faith and love," that is, faith working righteousness by love, are "the breastplate" in 1Th 5:8.
