As he walked along, he saw Levi son of Alphaeus sitting at the tax collector’s booth. “Follow me,” Jesus told him, and Levi got up and followed him. (Mark 2:14)
As a tax-collector, Levi was excommunicated from the synagogue and disqualified from being a witness in court. Isn’t it ironic that a man who couldn’t testify in court went on to write a book that does nothing but testify and has continued to testify to Jesus as the King and Messiah for over 2,000 years?
