Hank Hanegraaff, the host of the Bible Answer Man broadcast, discusses the great differences between Christianity and Islam—differences highlighted by the recent reversion of Hagia Sophia into a mosque. Hank notes that, paradoxically, just as Hagia Sophia is in process of completing its transition from monument to Messiah to Muslim mosque, the St. Nicholas Greek Orthodox National Shrine at Ground Zero in New York City is in its final stages of completion. As luminous as the architecture itself is the tradition and hospitality that the St. Nicholas Church will exemplify as the only non-secular building at Ground Zero.
