Where did John the Baptist lived?
John the Baptist was not a Christian, as we typically think of Christians. John lived and died before Christ's death and resurrection, so he had no opportunity to become a Christian, per se. However, John the Baptist clearly lived a life exclusively dedicated to obedience to God, which is obviously a virtue Christians are commanded to exhibit.
John was born for a special purpose. Given the Holy Priesthood at the age of eight years, it was his mission to be the forerunner to Jesus Christ. He told the people of the Messiah's coming and to make the people ready to receive him. He was The Baptist and baptized the Christ. John was one of the greatest teachers ever to have lived during his lifetime.
