I can't tell you how many times I have nutritionally counseled Christians who have told me that because they prayed over their food they should not be to concerned what they eat.
I am just stunned when I hear that.
So let me understand this thinking. Because we pray over our food, God is going to violate the very natural laws he put in place.
When it comes to food, the very food that He made and designed, for our bodies, we can tell Him, or imply, that because we prayed, that His design for the type of fuel we ingest doesn't really mean that much.
Does anyone here think that way? That we can pray over our food and that if we eat the worst junk it will not affect us?
Just so I am not misunderstood, I know God can un-poison a poison food. And I would not doubt at certain times He has saved people from illness or death. And I believe it is proper and right to give God thanks and pray for nourishment. So I am not suggesting that praying over our food is a useless endeavor.
