God is the biggest WHAT......

Recently heard a sermon from Graham Cooke. He tells his testimony with a statement that I think has really got me thinking. He feels that God has made us all so very differently. He's made us in a way that allows us to experience different parts of him the most. For Graham God is the kindest person he has ever known. For some He is the most loving, for others He is the most forgiving, for others the most gracious. What is He to you? God is the most_______ I've ever known. You fill in the blank.
