Yes, and Jesus was trying to teach his disciples that he was not God or divine when it was said he returned from the dead by asking for food. The Psalm you quote, God says does the creator of the earth need any food? Wow! How beautiful these two fit together. God is asking us to use the inteligence he gave us.
Yes, and by extension God is asking us to use the (higher) Cosmic Intelligence that we have access to. It is this intelligence, which is key to success but we had lost sight of this so long ago, and now look where we are.
When I can find a way to explain how to connect with this hub of intelligence, I will surly post it here. All I can say now is that it must be earned.
