Laws of logic are God’s standard for thinking. Since God is an unchanging, sovereign, immaterial Being, the laws of logic are abstract, universal, invariant entities. In other words, they are not made of matter—they apply everywhere and at all times. Laws of logic are contingent upon God’s unchanging nature. And they are necessary for logical reasoning. Thus, rational reasoning would be impossible without the biblical God. The materialistic atheist can’t have laws of logic. He believes that everything that exists is material—part of the physical world. But laws of logic are not physical. You can’t stub your toe on a law of logic.
