“God is not a subject for debate, because He is Who He is and What He is. We are told that the unbeliever, of course, does not agree with that; and that is perfectly true; but that makes no difference. We believe it, and it is part of our very case to assert it. Holding the view that we do, believing what we do about our God, we cannot in any circumstances allow Him to become a subject for discussion or of debate or investigation. I base my argument at this point on the word addressed by God Himself to Moses at the burning bush (Ex. 3:1-6). Moses had suddenly seen this remarkable phenomenon of the burning bush, and was proposing to turn aside and to examine this astonishing phenomenon. But, immediately, he is rebuked by the voice which came to him saying, ‘Draw not nigh hither: put off thy shoes from off thy feet, for the place whereon thy standest is holy ground.’ That seems to me to be the governing principle in this while matter. Our attitude is more important than anything that we do in detail, and as we are reminded in the Epistle to the Hebrews, God is always to approached ‘with reverence and with godly fear: for our God is a consuming fire’ (Heb. 12:28 and 29).
To me this is a very vital matter. To discuss the being of God in a casual manner, lounging in an armchair, smoking a pipe or cigarette or a cigar, is to me something that we should never allow, because God, as I say, is not a kind of philosophic X or a concept. We believe in the almighty, the glorious, the living God; and whatever may be true of others we must never put ourselves, or allow ourselves to be put, into a position in which we are debating about God as if He were but a philosophical proposition.”
