“Hell is empty and all the devils are here.”

Orthodoxy (1884)
Context: The church must not abandon its belief in devils. Orthodoxy cannot afford to put out the fires of hell. Throw away a belief in the devil, and most of the miracles of the New Testament become impossible, even if we admit the supernatural. If there is no devil, who was the original tempter in the garden of Eden? If there is no hell, from what are we saved; to what purpose is the atonement? Upon the obverse of the Christian shield is God, upon the reverse, the devil. No devil, no hell. No hell, no atonement. No atonement, no preaching, no gospel.
