"Some of my friends good-humoredly – and some a little bit severely – have called me a ‘mystic.’ Well I’d like to say this about any mysticism I may suppose to have. If an archangel from heaven were to come, and were to start giving me, telling me, teaching me, and giving me instruction, I’d ask him for the text. I’d say, ‘Where’s it say that in the Bible? I want to know.’ And I would insist that it was according to the scriptures, because I do not believe in any extra-scriptural teachings, nor any anti-scriptural teachings, or any sub-scriptural teachings. I think we ought to put the emphasis where God puts it, and continue to put it there, and to expound the scriptures, and stay by the scriptures. I wouldn’t – no matter if I saw a light above the light of the sun, I’d keep my mouth shut about it ’til I’d checked with Daniel and Revelation and the rest of the scriptures to see if it had any basis in truth. And if it didn’t, I’d think I’d just eaten something I shouldn’t, and I wouldn’t say anything about it. Because I don’t believe in anything that is unscriptural or that is anti-scripture."
