The ego is nothing but an illusion. It is not really afraid of God. Only when you decide to USE it do you experience its fearful perspective.
So if you withdraw your use of it, you also will no longer experience fear.
So the fear is not really yours, if it's just part of the ego's viewpoint, and the fear is not really the ego's, because the ego is just an illusion that can't experience anything without you.
So, where is the real fear? There is none.
