John the Baptist was the son of a Jewish prophet and thus a prominent son of Abraham and Jacob
[Israel]. (
Luke 1:5-17) John was sent by God as a forerunner of the Christ, to encourage all people to have faith in Jesus (
Mat 3:7-12) as God's Son. (
Mat 17:5) Announcing the arrival of God's anointed King over mankind was a wondrous job for John. Probably one of the last things he expected, however, was to be thrown into prison. No doubt having some doubts about Jesus and his own task, it was from those bonds John sent his disciples to inquire of Jesus if he really was the promised Messiah. Keeping faith, no matter what happens to us, is very important. Jesus lumped hearing about and having faith in the good news of God's Kingdom, (
Mat 24:14) with having eyesight restored or being raised from the dead; thus the most important thing in life. (
Mat 13:44)
