You: It is obvious that we cannot be sure what happens to one after death, so we cannot be sure that there is any justice there.

Aaron: On the contrary, our faith teaches exactly what happens after death, and we can be certain that there is justice.

You: Your faith passes along tenants and repeats traditional ideas, it proves nothing. We cannot see the afterlife therefore we cannot tell what is happening there.

Aaron: Proof is not always a good thing. I know heaven in my heard just as well as I know God there.

You: That is completely irrelevant. Unless you can prove God and can prove an afterlife, this argument is without any meaning what so ever.
