So here....
I will throw an unpopular opinion in to the mix.
Why does prayer over food have to be about self?
A whole a lot of work went in to getting that food to you.
One of the plights on earth that you did not mention above is the farmer. They are one of the few people left in the richest country on earth that work beside their migrant workers to bring their product to the market. Between big commercial farms, lack of water in California (one of our biggest growers in the US) and good old Monsanto buying the rights to all the seed produced - farmers are a dying breed.
What about packers working in produce sheds, truckers who haul it people who own produce stands and sell it with pride?
Why cant a prayer be a moment of thanks and recognition that what is in front of us has required hard work? Why does it have to involve anything whatsoever to do with what the JWs taught us?
I am at work today (yes! on a sunday!) and dont have time to look for it but someone (?) once said that it is a poorer man who bows his head in thanks to nothing" (sic)
I am not offering this thought up as a disagreement really.
Its more like food for thought - pun intended!
