It's 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.”

- Charles Haddon Spurgeon
