Using the Qur'an to Explain the Incarnation of Jesus to Muslims

Many Muslims ask their Christian friends questions like, "If Jesus is God, how can he die?" or "If Jesus is God, how can he be born?" Some Muslims even suggest that the Christian doctrine of the Incarnation is absurd or illogical. But if the Christian view is illogical, so is Islam, because Islam teaches something similar about the Qur'an. According to Islamic theology, the Qur'an has two natures: an eternal nature and a physical nature. Allah's eternal Word (which has no beginning and no end) enters creation as a physical book (which has a beginning and an end). The physical nature can be destroyed, while the eternal nature can't. Hence, if Muslims want us to take their objections to the Incarnation seriously, they have to reject Islam!
