This is one of the first issues that come up when taking the Bible or the Koran seriously; if we really need these books then what about the people who died before them? Or people who live miles away and have never heard of Jesus or Mohammed. It seems to me that Christians take this issue seriously or they wouldn't try so hard to distribute Bibles or otherwise spread the word. Since it's an obvious question and it isn't much discussed I take it there's an obvious answer but I don't know it. So can anyone tell me?
