John Erskine on Preaching

Some good advice on preaching, from 18th century Scottish preacher and theologian, John Erskine:

I need not caution you against affecting a florid haranguing style, nor tell you that the more of scripture there is in a sermon so much the better, as we ought not only to declare truth, but to declare it in the words which the Holy Ghost teacheth. There is an energy and force in the words of the Bible, which all the wisdom and eloquence of men can never equal, and which by the influences of the Spirit produces effects peculiar to itself.
