How do you know your irrational faculties are reliable?
Christians will often claim that non-believers cannot trust their reasoning, because in a non-theistic universe, brains are just meat that didn’t evolve for truth.
But even in a theistic worldview, don’t you have to rely on your senses and rational faculties to know that God exists? If God didn’t exist, the most bulletproof, irrefutable apologetic would be based on rational faculties that come from a brain that is just matter in motion. If you were wrong, you’d have no way of knowing it, just like non-believers.
