The Matrix

In the second Matrix movie, it is interesting to see that there are many humans who do not agree that Morpheus's firm beliefs.  This is a noticeable difference from the first movie where Cypher is the only freed human who does not support Morpheus.  The fledgeling religion revolving around Neo is challenged by some of the more sceptic residents of Zion, the last human city.  Thus far, Morpheus has taken the mantle of a profit preaching his beliefs to the people of Zion.  At the festival, so powerful is Morpheus's own belief, that the people's fears are allayed and they are swayed by his precepts.  In our own world, it is very true that the most convincing missionary is also a firm believer in the proposed religion.  People want to be unafraid and confident; Morpheus successfully offers them this in his speech to Zion and reaffirms their belief in Neo.
