There is nothing Satan can do to alter or undermine the fact that we are saved. Not “angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other created thing, shall be able to separate us from the love of God, which is in Christ Jesus our Lord” (Rom. 8:38-39). But, what he can do is erode our assurance and confidence that we are saved. Our salvation, our standing with God, does not fluctuate or diminish with our success or failure in spiritual battles. But Satan is determined to convince us that it does.
