But doesn't this create a logical paradox? In that, nothing inherently except a personal choice, would distinguish God's contact with man in Christian or Islamic texts, right? In that you would only pick one over the other - Pepsi or Coke, in effect, just on a divine scale. But if you accept that as true - that God revealed his plans to man - then you have to accept the revelation to Mohammed as a valid discussion with God. To do that though, then you have to accept God told Mohammed that Christians got his will wrong; in effect, that they screwed up and Islam is the most current iteration of God's will?
