"The Star," by Arthur C. Clarke. A parable, really, of the religious person's efforts to reconcile God's goodness with the evils of the world.
P.S. Notice that the Honda robot is named Asimo! Alot kinder than that Will Smith Schlock "I Robot"
... Yep, Clarke's "The Star".
With a troubling, yet unforgettable final line:
"My God ! Why did these people have to be thrown into the fire, that the sign of their passing might be seen over Bethlehem!". . .
