One of the best analogies of faith is the Indiana Jones scene in "Last Crusade" where he has to walk across the chasm on an invisible bridge. You don't know the bridge is there till your foot goes out into the dark. To have the faith, you either have to believe that you won't hit, or you have to be ok with the possibility of splatting.
We all pretty much understand that a community under Christ would be one of sharing possessions and hospitality. A 15-and-a-half-year-old can only HOPE that we'll put that into action, and spread the love through gifts of cars!
