John the Baptist's ministry grew in popularity, as recounted in Matthew 3:5–6: "People went out to him from Jerusalem and all Judea and the whole region of the Jordan. Confessing their sins, they were baptized by him in the Jordan River." To be baptized by John was to admit your sin and repent of it—which was, of course, a great way to be prepared for the Savior’s coming. The repentance associated with John’s baptism also kept the self-righteous out of the water, as they did not see themselves as sinners. For the self-righteous, John had stern words, calling them a "brood of vipers" and warning them not to rely on their Jewish lineage for salvation, but to repent and "bear fruit in keeping with repentance" (Matthew 3:7–10). People of that day simply did not address leaders, religious or otherwise, in this manner for fear of punishment. But John's faith made him fearless in the face of opposition.
