Our Provider?

I saw a bumper sticker a few days ago that read “Jesus Christ - Our Provider”.  The thought that straight away crossed my mind was “stop working for a few months and see who your provider is”.  It’s not that I have a problem with Christianity (or other people’s beliefs in general), but I just don’t see what religion or spirituality or faith have to do with our responsibility for earning a living and for our lives in general.  It’s one thing to be grateful for our world, for our skills, for opportunities, or whatever.  It’s quite another to believe that God will put bread on our tables without any effort on our part.  God does not micro-manage our lives.
