You must be born again

George Whitefield (1714–1770) is thought by some to have been the greatest preacher since the day of the Apostles.

As he travelled around, he would often preach on the same text.  

One of Whitfield’s supporters once asked him:

Mr Whitfield, “Why do you so often preach on that text, “You must be born again?”

Whitfield replied: "Its because, “You MUST be born again!”"
