“No scientist ever begins his work de novo; while he works with the methodological questioning of what he has already known he builds on knowledge already achieved and engages in a movement of advance. But it is one of the worst characteristics of theological study, whether in biblical interpretation or in dogmatic formulation, that every scholar nowadays thinks he must start all over again, and too many give the impression that no one ever understood this or that until they came along.”

“Every sentence I utter must be understood not as an affirmation, but as a question.[A caution he gives his students, to be wary of dogmatism.]”

“The Biblical educator must not only have a Christian understanding of the material, he must have a Biblical understanding of the student. If he does not, then the result will be a hybrid Christian methodology employed to achieve a humanistic goal.”

“A zealous man in religion is pre-eminently a man of one thing. It is not enough to say that he is earnest, hearty, uncompromising, thorough-going, whole-hearted, fervent in spirit. He sees one thing, he cares for one thing, he lives for one thing, he is swallowed-up in one thing — and that one thing is to please God. Whether he lives — or whether he dies; whether he has health — or whether he has sickness; whether he is rich — or whether he is poor; whether he pleases man — or whether he gives offence; whether he is thought wise — or whether he is thought foolish; whether he gets blame — or whether he gets praise; whether he gets honor, or whether he gets shame — for all this the zealous man cares nothing at all. He burns for one thing — and that one thing is to please God, and to advance God's glory. If he is consumed in the very burning — he is content. He feels that, like a lamp, he is made to burn, and if consumed in burning — he has but done the work for which God appointed him. Such a one will always find a sphere for his zeal. If he cannot preach, and work, and give money — he will cry, and sigh, and pray. Yes, if he is only a pauper, on a perpetual bed of sickness — he will make the wheels of sin around him drive heavily, by continually interceding against it. If he cannot fight in the valley with Joshua — then he will do the prayer-work of Moses, Aaron, and Hur, on the hill. (Exod. 17:9-13.) If he is cut off from working himself — he will give the Lord no rest until help is raised up from another quarter, and the work is done. This is what I mean when I speak of "zeal" in religion.”

“As a man's knowledge grows, and his power increases, the road he takes grows ever narrower, until at last he does only and wholly what he must.”

“I often wonder what Einstein would have done in my position. At Peterson, I kept an Einstein poster in my room, the one that says 'Imagination is more important than knowledge.' Einstein was smart, maybe even as smart as Laserator, but he played it way too safe. Then again, nobody ever threw a grappling hook at Einstein. I like to think he would have enjoyed my work, if he could have seen it. But no one sees anything I do, not until it's hovering over Chicago.”
