I do not believe that any man can preach the gospel who does not preach the law. The law is the needle, and you cannot draw the silken thread of the gospel through a man's heart unless you first send the needle of the law to make way for it. If men do not understand the law, they will not feel that they are sinners. And if they are not consciously sinners, they will never value the sin offering. There is no healing a man till the law has wounded him, no making him alive till the law has slain him.
C.H. Spurgeon
