Here's a beautiful quote from Graham Cooke about the heart of God:
"The glory of God is the nature of God - that He is good. God is good, and He always will be. He's the kindest person we know.
"He is consistent. He will never change His heart towards you, no matter what you do. He cannot be anything other than what He is. He's a covenant maker and a covenant keeper, and He's good.
"We live in His faithfulness and His security. He will come and do all that needs to be done.
"God is our only security. His great heart will sustain us in any and all situations."
(from "The Nature of God" by Graham Cooke)
