faithful--alluding to "faith" (Th2 3:2) : though many will not believe, the Lord (other very old manuscripts read "God") is still to be believed in as faithful to His promises (Th1 5:24; Ti2 2:13). Faith on the part of man answers to faithfulness on the part of God. stablish you--as he had prayed (Th2 2:17). Though it was on himself that wicked men were making their onset, he turns away from asking the Thessalonians' prayers for HIS deliverance (Th2 3:2 : so unselfish was he, even in religion), to express his assurance of THEIR establishment in the faith, and preservation from evil. This assurance thus exactly answers to his prayer for them (Th2 2:17), "Our Lord . . . stablish you in every good word and work." He has before his mind the Lord's Prayer, "Lead us not into temptation, but deliver us from evil"; where, as here, the translation may be, "from the evil one"; the great hinderer of "every good word and work." Compare Mat 13:19, "the wicked one."
