Mark Batterson in his book "The Circle Maker" asks a very provocative question based upon a question that God asks Moses; "Is there a limit to my power?" (Numbers 11:23) GNT.
"Are your problems bigger than God, or is God bigger than your problems? Our biggest problem is our small view of God. That is the cause of all lesser evils. And it's a high view of God that is a solution to all other problems. Have you answered the question? There are only 2 options: yes or no. Until you come to the conviction that God's grace and power have no limits, you will draw small prayer circles. Once you embrace the omnipotence of God, you'll draw ever enlarging circles around your God-given, God -sized dreams. "
