Jamieson, Fausset and Brown on Romans 8:37

37. Nay, in all these things we are more than conquerors, through him that loved us--not, "We are so far from being conquered by them, that they do us much good" [Hodge]; for though this be true, the word means simply, "We are pre-eminently conquerors." See on Ro 5:20. And so far are they from "separating us from Christ's love," that it is just "through Him that loved us" that we are victorious over them.
