Jesus said, "I have come that they may have life, and have it to the full." That's the offer of Christianity, from God himself.
Jesus touched people, and they changed: the blind had sight, the lame walked, the deaf heard, the dead were raised. To be touched by God, in other words, is to be restored, to be made into all God means us to be. That is what Christianity promises to do--make us whole, set us free, bring us fully alive.
