". . . whatever topic you preach on and whatever text you choose, there ought not to be in your whole repertoire a single sermon in which from beginning to end you do not convey to your hearers the impression that what you want to impart to them, you do not think it possible to impart to them in any other way than as a correlate and consequence of the eternal salvation of their souls through the blood of Christ, because in your own conviction that alone is the remedy which you can honestly offer to a sinful world."
