If I say to you, "Believe on the Lord Jesus Christ," you will reply, "Oh, believe! I have heard that word till I am sick and tired of it. Scarcely a week but I hear it in the church, or at a prayer-meeting, or at some drawing-room meeting." You have all heard it over and over again; I don't suppose there is a child here over five years of age but can repeat that text. What you want is, to know how to believe--what it is to believe.
Some of you say, "We all believe that Christ came into the world to seek and to save the lost; and that he that believeth shall be saved." But the devils believe, and are not saved. Ay, they believe and tremble! You must believe _on_ the Lord Jesus Christ, and not merely _about_ Him, and then you will know what _salvation_ is.
