I have been reading the Sermon on the Mount from the Gospel of Matthew.  I have read these passage hundreds of times in the past and over the last six months have worked through it with a friend. 

I have been struck by the verse in Matthew 5 where Jesus says, “You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men.”
