Trust.

"You know, we make a list and pray about those needs. And then we fail to recognize what God is in fact doing to answer the prayers requests on our little list—sometimes He is telling us 'No.' And sometimes He is not even responding to us because He has something else He wants to do. But He doesn’t get glory. He doesn’t get trust. There is no fear of God because our list is the biggie. And we say, 'God, as soon as You do something about my list, I’ll know that You exist.' Hey wait a minute. In the beginning God created. The Bible does not set out to prove to you the existence of God. It assumes it. It asks you to respond to it, to believe in Him and to trust Him no matter what." - David Hocking, Attributes of God on Blue Letter Bible Institute.
