The difference between Jesus and all the other wannabe "Messiahs" is that Jesus was raised from the dead. His bodily resurrection, really a living, breathing, eating, solid new body, is the source of our hope, the most important foundation of the Good News, and the reason we can live in the ways Jesus called us to live without fear of death, but with confidence that we to will share in a resurrection like his.
1 Corinthians 15
