Many people have given their life to destroy the faith of people in Christ. It's not hard to destroy, to pull down. Anyone can undermine by ridicule, satire and skeptical objections. People seek to discredit the Bible and call it a book of myths. They mock the miracles and tell us that Christ did not rise from the dead.
Theories never satisfy the soul of a person who yearns for truth.
There is one big problem with that, all of their leaders are dead. Their followers make pilgrimages to their shrines. Dead men can't help living men. We could make personal success our god. Every person could do that which is right in his own eyes.
