When thou art by sin driven to make a stand, so that thou must either serve it and rush at the command of it into folly, like the horse into the battle, or make head against it to suppress it, what dost thou say to thy soul? what dost thou expostulate with thyself? Is this all,—”Hell will be the end of this course; vengeance will meet with me and find me out?” It is time for thee to look about thee; evil lies at the door. Paul’s main argument to evince that sin shall not have dominion over believers is, that they “are not under the law, but under grace,” Rom. 6:14. If thy contendings against sin be all on legal accounts, from legal principles and motives, what assurance canst thou attain unto that sin shall not have dominion over thee, which will be thy ruin?
