I read “The Divine Dramatist” a few years ago, it truly is an awful biography of Whitefield. I missed the gem Piper found, click the link to see it. Whitefield’s journals are the best starting point to get into the man.
In the most cynical, unsympathetic, and misleading biography I have ever read, there is a magnificent paragraph about Benjamin Franklin and George Whitefield.
The Deist and the Calvinist were best friends. “Franklin became Whitefield’s best American friend and, reciprocally, Whitefield was Franklin’s only evangelical friend” (The Divine Dramatist, 220).
