Charles Spurgeon Commentary Mark 1:23-24

"And straightway there was in their synagogue a man with an unclean spirit; and he cried out, saying, What have we to do with thee, Jesus thou Nazarene? art thou come to destroy us? I know thee who thou art, the Holy One of God." — Mark 1:23-24 (ASV)

And there was in their synagogue a man with an unclean spirit; and he cried out, saying, Let us alone;

How often that is still the cry of sinners: "Let us alone. Why do you not hold your own views, and let us alone?" Yes, the devils, and those whom they control, still say, "Let us alone."

But it is a part of the gospel to attack that which is not the gospel, and it is as much the duty of the minister of the gospel to denounce error as to proclaim truth. If we do so, the old cry will still be heard: "Let us alone. Let us alone."
