Who is God (The Enemy) from The Screwtape Letters and what is their importance?

God is shown to be a benign, loving presence, ever ready to respond to His children's needs, thoughts, and concerns. Although He is fighting a cosmic battle with the Devil for every human soul, He waits upon human will to take action and always fights fairly and like a gentleman. The foundation of His throne and being is love; He is regretful the devils cannot understand that. He is shown as loving these "amphibious" human creatures—half spirit and half flesh—with a deep and abiding love.
