If his followers lied about Christ why did they not recant. They were persicuted, humiliated, hunted down and killed. I wouldn't die for a lie, how about you?
As I noted upthread, either some people will die for a lie, or a wide variety of religions (Wahabi Islam, Catholicism, Lutheranism, Judaism, etc) are all the truth (which would appear to be logically impossible on its face).
