You: Who says that they are wrong?

Aaron: God.

You: There are a good number of people all around the world who say that their enemies are wrong and that God agrees.

Aaron: Those people are wrong as well.

You: Fine. Now tell me, how can I tell the difference between you and them? You both claim to speak for God.

Aaron: The difference is that I am right while they are wrong. They believe in a false God.

You: If asked, they would say the same thing about you.

Aaron: And they would be wrong.

You: You will not be able to convince me that. It is impossible for me to know who is right without my first knowing the mind of God.

Aaron: Your mind seems to be completely closed on this subject. In that I will obviously not be able to convince you, I will save myself the effort of trying.
