John the Baptist is regarded as the precursor of Jesus Christ. A very well-known preacher, he gave sermons about the proximity of God's Final Judgment. He asked people to repent for their sins and baptized those who apologized in self-preparation for the Lord to come. According to the Scriptures, it was John only who recognized Jesus and decreed Him as the Messiah of the people. The four Gospels (Matthew, Mark, Luke, and John), the Acts of the Apostles, and the Jewish historian Josephus' Antiquities of the Jews comprise of the only sources of information about the life of John the Baptist.
