I approach every part I'm asked to do and decide to do from exactly the same angle: who is this person, what does he want, how does he attempt to get it, and what happens to him when he doesn't get it, or if he does?
We want to worship a living God. I have not seen anything but God all my life, nor have you... He is everywhere, saying, "I am." The moment you feel "I am," you are conscious of Existence. Where shall we go to find God if we cannot see Him in our own hearts and in every living being?
