Ephesians 6:10

“Finally, my brethren, &c.] This is the conclusion of the apostle's exhortations, in which he addresses the saints as his brethren; which appellation he uses, not merely as a familiar way of speaking among the Jews, but in regard to them as regenerate persons, and of the same family and household of God with himself; and he calls them so, to show his humility, and as a proof of his affection to them, and with a design to encourage them to their duty, as follows: be strong in the Lord, and in the power of his might; which is directed to, partly on account of the things before exhorted to, which could not be performed in their own strength; and partly with respect to their many and potent…”

“my brethren--Some of the oldest manuscripts omit these words. Some with Vulgate retain them. The phrase occurs nowhere else in the Epistle (see, however, Eph 6:23); if genuine, it is appropriate here in the close of the Epistle, where he is urging his fellow soldiers to the good fight in the Christian armor.

He was not unaware that in the discharge of their duties they would need strength from above. He knew that they had great and mighty foes, and that to meet them, they needed to be clothed in the panoply of the Christian soldier. He closes, therefore, by exhorting them to put on all the strength which they could to meet the enemies with which they had to contend; and in the commencement of his exhortation he reminds them that it was only by the strength of the…”

“Brethren - This is the only place in this epistle where he uses this compellation. Soldiers frequently use it to each other in the field. Be strong - Nothing less will suffice for such a fight: to be weak, and remain so, is the way to perish. In the power of his might - A very uncommon expression, plainly denoting what great assistance we need as if his might would not do, it must be the powerful exertion of his might. Ephesians 6:11”

“6:10-20 Paul’s final word is to remind the believers of the devil’s opposition and urge them to protect themselves with all of God’s armor.”
