What the Bible says about Magnitude of John the Baptist's Work
(From Forerunner Commentary)

Mark 11:32 Mark 11:32 provides insight as to how the people perceived John. Clearly, the common people considered him a prophet, and indeed, he was. This also shows that the highest Jewish authorities were fully aware of his reputation as a prophet and feared it. We can begin to see that in many respects the magnitude of John's work was similar to Jesus'. John W.
