Nathaniel, when told by his good friend Phillip that he has found The Messiah, the one promised by Moses and the prophets, reacts in disbelief. His disbelief, however, isn't because the claim is farfetched. Many people during that time were looking and hoping for the promised one. Instead, the disbelief is generated by one word; "Nazareth." Nothing good comes from there. 

Nathaniel nearly misses a chance to walk with Jesus because of a built-in prejudice. Are we really any different? What have we missed out on because of our base-level reactions against others?
