Memoirs of the Life of David Marks: Early Free Will Baptist Leader

"It appears from this that his labors in the denomination of Free-will Baptists, to whichhe belonged, were almost unbounded. Probably no man living has done more for that order than he. He travelled and preached over the whole country from the Ohio river to the remote parts of New England-at the cost of immense and self-sacrificing labour."---From the burial sermon of Charles Finney over David Marks.
