For sin shall not have dominion over you: for ye are not under the law, but under grace. (Romans 6:14)
in will reign if it can: it cannot be satisfied with any place below the throne of the heart. We sometimes fear that it will conquer us, and then we cry unto the Lord, "Let not any iniquity have dominion over me. This is His comforting answer: "Sin shall not have dominion over you. " It may assail you and even wound you, but it shall never establish sovereignty over you.
If we were under the law, our sin would gather strength and hold us under its power; for it is the punishment of sin that a man comes under the power of sin. As we are under the covenant of grace, we are secured against departing from the living God by the sure declaration of the covenant. Grace is promised to us by which we are restored from our wanderings, cleansed from our impurities, and set free from the chains of habit.
We must lie down in despair and be "content to serve the Egyptians" if we were still as slaves working for eternal life; but since we are the Lord's free men, we take courage to fight with our corruptions and temptations, being assured that sin shall never bring us under its sway again. God Himself giveth us the victory through our Lord Jesus Christ, to whom be glory forever and ever. Amen.
