Which Old Testament prophet also described John the Baptist as a voice crying in the wilderness?
The prophet Isaiah is the Old Testament prophet who described John the Baptist as the voice of one crying in the wilderness, saying, 'Prepare ye the way of the Lord, and make his paths straight.' This prophecy is cited in the Gospel account as being spoken of John.
Les explains that John the Baptist was spoken of by the prophet Isaiah, who described him as the voice of one crying in the wilderness, 'Prepare ye the way of the Lord, and make his paths straight.' He notes he had earlier taken the class back to Malachi, but Isaiah also prophesied of John. This connects to John’s baptism in Jordan, where people were baptized by him and confessed their sins. The context also stresses that the Kingdom of Heaven was at hand because the King, the Lord Jesus, had come.
