This quote comes from Joseph Beaumont Wakeley's Anecdotes of the rev. George Whitefield, M.A., with biographical sketch:
There is such a thing as spiritual merchandise. Solomon says, in regard to wisdom, "The merchandise of it is better than the merchandise of silver; and the gain thereof, than fine gold." Mr. Whitefield, on one occasion while preaching in Philadelphia, cried out in the midst of the sermon, "I am going to turn merchant to-day. I have valuable commodities to offer for sale, but I say not, as your merchants do, If you will come up to my price I'll sell to you; but, If you will come down to my price; for if you have a farthing to bring you cannot be a purchaser." They were urged to "buy the truth;" to "buy wine and milk without money and without price."~George Whitefield/Joseph Beaumont Wakeley (Anecdotes of the rev. George Whitefield, M.A., with biographical sketch, page 133, 1872)
"See from the Rock a fountain rise;
For you in healing streams it rolls;
Money ye need not bring, nor price,
Ye lab'ring, burdened, sin-sick souls."
During the sermon a broken-hearted man took courage, and his language was,
"In my hands no price I bring;
Simply to the cross I cling."
He bought without money and without price, and returned home in possession of true riches.
