Its not sin, nor the devil we are saved from, rather the wrath of God toward sin; thus we are saved from God, by God. As stated in another post, it is God’s wrath toward the unnaturalness of sin that makes the issue. Romans 1:18ff tells us that His wrath is revealed against the ungodliness and unrighteousness of men and that wrath brings about death (Rom. 6:23) – by the way, death being the ultimate enemy, in the sense that it is the ultimate event of the result of sin (Gen. 2:17). Death is also the final battle/victory (1 Cor. 15:54-57) . . . but, more on that later.
