These men distinguish between a rationalist and a reasonable (logical) person. The rationalist tries to determine all truth through reason alone, the reasonable person however only tries to discover truth, not determine it. They use logic to test the truth of their statements about God. *Side note- that last sentence sounds like what you might call a "faith scientist". A person using scientific observations and logic on the path of discovery of the unseen world of faith.
Here was a question posed to the authors which you may have posed at some point yourself.
"The Bible says that God can do the impossible. Doesn't that mean He is not bound by logicial limitations?"
Oooo, sounds like a tough question doesn't it? Let's see how Ronald and Norman logically answer this:
****God can do what is humanly impossible, but not what is actually impossible. (There is a difference between what we know to be impossible for humans and what is logically impossible for God.)
****Hebrews 6:18 says it is impossible for God to lie. So there are actual things that are impossible for God to do. They just not be things that you are thinking of from your human perspective.
****James 1:13 says God cannot be tempted.
****2 Timothy 2:13 says It is impossible for him to deny his oath. He is a perfectly good God who cannot do evil.
God cannot make a square circle. He cannot make a triangle with only 2 sides, neither can anyone else, human, angel or demon. These things are self-contradictory and cannot exist. They are logically impossible.
How does that change your thinking or challenge it? Points to ponder for sure. I appreciate the fact that God requires Himself to be logical, how about you? It stretches my understanding to ponder how the things that are impossible for God to do are related to "absence of evil" in his character? How does this bless you?
