Thanks for posting this. I found it a bit sophomoric, however. Here's why:
The jug of milk exists in the physical plane. It cannot exist anywhere else.
The method most Christians use in prayer is technologically wrong. The science of real prayer has been virtually lost for approximately 1600 years. All people do now is ask for stuff, thank God for what they do have, and praise Him a little.
This is because they have an old idea of what and who the Divine Presence is. They treat prayer and the Divine Intelligence that moves through all things like a kind of Santa Claus. You go and kneel on your knees and ASK for stuff and expect "Santa" to give you what you ask for.
No wonder prayers are not answered!! No wonder people have stopped believing in God!
