I was thinking about this very subject recently and wondering why dinner time is the default time for prayer. There is so much more to be grateful for than just food.
Might be just me but I don’t remember there being a lot of emphasis on prayer. Why would there be when we can leave that up to the experts, the FDS.
It also seems to me that the JWs don’t show much gratitude. We said thanks for meetings and what the FDS provided bla bla bla. But I don’t remember ever seeing the majority show any gratitude for the little things in life. And I don't remember any of it seeming very sincere.
