What the Bible says about John the Baptist's Humility
(From Forerunner Commentary)
Consider this situation. Jesus later testifies that of all men born none was greater than John the Baptist. Earlier in his ministry, John had attracted a great deal of attention. Crowds followed him everywhere and seemed to hang on his every word. Now his bewildered disciples watch the fickle crowds leaving John to hear and follow a new voice. To compound the problem, John himself had extolled Jesus and seemingly set off the exodus of his followers to Him. So in their frustration at not wanting to see John in any sort of disadvantage, they enter into an argument with others around them.
Their question is, "John, this other fellow, this Jesus, is growing great, but you are diminishing. Why? Have you lost your touch? What does He have that you do not?" John's reply reveals a great deal about his character: He is a humble man, not jealous, presumptuous, envious, or bitter. He exhibits no rancor but a generous spirit. He knows who is guiding and directing His servants. He rejoices in the operations that he, as a servant, can perform in being the forerunner of Christ. A paraphrase of his response might be: "I have to work at whatever God charges me and be content with what He gives me. It is not as if Jesus is stealing disciples from me but that God is giving them to Him." He undoubtedly perceives God as His sovereign Ruler.
