“Yea…that we shall see the great Head of the Church once more . . . raise up unto Himself certain young men whom He may use in this glorious employ. And what manner of men will they be? Men mighty in the Scriptures, their lives dominated by a sense of the greatness, the majesty and holiness of God, and their minds and hearts aglow with the great truths of the doctrines of grace. They will be men who have learned what it is to die to self, to human aims and personal ambitions; men who are willing to be ‘fools for Christ’s sake’, who will bear reproach and falsehood, who will labor and suffer, and whose supreme desire will be, not to gain earth’s accolades, but to win the Master’s approbation when they appear before His awesome judgment seat. They will be men who will preach with broken hearts and tear-filled eyes, and upon whose ministries God will grant an extraordinary effusion of the Holy Spirit, and who will witness ‘signs and wonders following’ in the transformation of multitudes of human lives.”
Arnold Dallimore, George Whitefield, Vol. 1 (London: Banner of Truth Trust, 1970), p. 16.
