In a move that sets the world's religions into opposing camps, Abraham ejects his first born son Ishmael and Ishmael's mother Hagar into the desert. The ostracized mother and son evolve into what we now know as the Arabic nations and from them the Muslim world. From Isaac, Sarah's son, the Jewish nation begins its arduous journey across the middle east, into Egypt and eventually settling into Israel. Christianity arises.
Now, five or six thousand years later, we are with Abraham, his wife, Sarah, and his second son Isaac.
What if Hagar and Ishmael came back for dinner?
