What did Jesus preach when he went from town to town in Galilee? "Accept me as your Lord and Savior?" "I am the Son of God, have faith in me?" "Love, love, love?" "Be baptized and go to Church on Sundays?" The evidence from the gospels leads one to conclude "none of the above."
MT 4:17 (using the translation of the Jerusalem Bible) "From that moment [= once John the Baptist had been arrested] Jesus began his preaching with the message: `Repent, for the Kingdom of heaven is close at hand.'"
Comment: A word must be said about each of these three elements of Jesus's message, namely the "repent", the "kingdom of heaven", and the "close at hand."
