I have been in infrequent communication with a skeptic friend. He posed a challenging question I am not sure how to address, so I thought I'd see if I could get some help from those on the PB:
"The main argument I have against Christianity is that there is absolutely no basis for determining which revelation of which god is the correct revelation and true God. For example, whenever I hear Christians critique the religion of Islam, it's always on the basis of tenets of Christianity...but how do they know to accept as their ultimate presupposition that Christianity is true and not Islam? Just critiquing apparent contradictions in the Koran doesn't help their case either if we're talking about ultimate presuppositions. If one accepts Islam to be true, it can stand on its own presuppositions and foundation regardless of how it appears through Christian or other-religious eyes. So again, my question is: out of the countless multitudes of religions based on special revelation, how do you know yours is the right one?"
