The Gospel saves some and hardens others

"I shall end this postscript with observing, that when the popular preachers can find no other way of showing their contempt of the simple belief of the truth, as the sole requisite to justification, they call it the faith of devils. Yet, however keen the intended reproach be, it can have weight with none but those who are swayed by sound instead of sense. For, according to the Scripture, the same truth which saves Christ's people, torments the devils. So we find them saying, 'what have we to do with thee, Jesus, thou Son of God? Art thou come hither to torment us before the time?' They believe, they hate, and yet they tremble at that truth which Christ's people believe, love, and find salvation in." - Robert Sandeman, Theron And Aspasio, Pg. 346
