Two Unmentionable Choices

Let’s go back to the ungodly thinking trilemma. Let’s look at the way ungodly thinkers filter possibilities to eliminate divine revelation. We see how this closed-mindedness comes from the way naturalism removes the choice of divine revelation without processing the thought. But revelation alone provides a true premise. We are irrational if we reason from a premise we can’t prove. The human mind can’t find truth. We can challenge any conclusion of the human mind, so it requires further proof. The fallen human mind only finds opinions. And since sound reasoning must have a true premise, naturalism forces ungodly thinkers to be irrational. Ungodly thinkers are irrational when they try to challenge God. They know better. God already revealed Himself to them. God revealed what humans can know about the Godhead to them. And He revealed many other facts to them, so they’re without excuse.
