We know this sounds heartless, but it's true: it simply was not Jesus's driving ambition to heal the sick and meet the needs of the poor, as much as he cared for them. He was sent into the world to save people from condemnation (John 3;17), that he might be lifted up so believers could have eternal life (3:14-15). He was sent by the Father so that whoever feeds on him might live forever (6:57-58). In his important work on the missions of Jesus and the disciples, Andreas Kostenberger concludes that John's Gospel portrays Jesus's mission as the Son sent from the Father, as the one who came into the world and returned to the Father, and as the shepherd-teacher who called others to follow him in order to help gather a final harvest. If Kostenberger is right, this is a long way from saying that Jesus's fundamental mission was to meet temporal needs.
