George Whitefield: A Biography, with special reference to his labors in America. R Belcher

Whitefield, that he had given up his business, and was gone to teach the Indians with whom he used to trade. Nor had his usefulness stopped here: he heard of a drinking club, which had attached to it a negro boy remarkable for his powers of mimicry. This boy was directed by the gentlemen who composed the club to exercise his powers on Mr. Whitefield: he did so, but very reluctantly; at length he stood up and said, "I speak the truth in Christ, I lie not; unless you repent, you will all be damned." This unexpected speech had such an effect as to break up the club, which met no more.

      We add a few paragraphs from Seward's journal, who soon after sailed for England to promote the interests of Georgia, and who died in the parent country. They date from the 24th to the 26th of April. "Came to Christopher Wigner's plantation in Skippack, where many Dutch people are settled, and where the famous Mr. Spalemburg lately resided. It was surprising to see such a multitude of people gathered together in such a wilderness country, thirty miles distant from Philadelphia. Mr. Whitefield was exceedingly carried out, in his sermon, to press poor sinners to come to Christ by faith, and claim all their privileges; namely, not only righteousness and peace, but joy in the Holy Ghost; and after he had done, our dear friend Peter Bohler preached in Dutch, to those who could not understand Mr. Whitefield in English."
