God and Truth
God is a God of truth. He cannot lie; He cannot contradict Himself; He will not fail to keep His word. You can depend on these truths when living your life or when constructing your theology.
C. S. Lewis did so with confidence because he understood that what to us are “rules” of logic and truthfulness (like the law of non-contradiction) are simply the practical articulation of who He is as a God of covenant faithfulness. He therefore “owns” those rules in a far more profound sense than just having arbitrarily made them up and imposed them. And that is why Aslan can ask the searching rhetorical question, “Do you think I wouldn’t obey my own rules?” (VDT 170).
