I do not believe that any man can preach the gospel who does not preach the Law. Lower the Law and you dim the light by which man perceives his guilt; this is a very serious loss to the sinner rather than a gain; for it lessens the likelihood of his conviction and conversion. I say you have deprived the gospel of its ablest auxiliary [its most powerful weapon] when you have set aside the Law. You have taken away from it the schoolmaster that is to bring men to Christ. they will never accept grace till they tremble before a just and holy Law. Therefore, the Law serves a most necessary purpose, and it must not be removed from its place. The Law cuts into the core of evil, it reveals the seat of the malady and informs us that the leprosy lies deep within. They must be slain by the Law before they can be made alive by the gospel.
~ Charles Spurgeon
