Who is the "he" who needs a concept of "faith" ? Certainly not the "God-self" any more than we have "selves" which would use the word "faith" to describe our expectation that the sun will rise tomorrow. (compare with Incas sun-sacrifices etc). If we argue that we don't need "faith" because we have "evidence", the Rev will argue he also has "evidence" for his particular version of the "God concept".

The only "faith" that he may admit to is that "existence" has a "purpose", for the alternative cannot be contemplated. His choice perhaps to call all existence "God" effectively sidesteps the traditional "faith in the existence of God" debate for him.
