The idea expressed by stocwatch that the apostles willing died is worth more thought than it has been given. The issue is not that these apostles "believed" in something that had been told to them be someone else but had no way to test it. The issue is that they had been told by Jesus that he ws the Christ and that he would die and rise again and than they saw him and talked to him, so they knew it was true. David Koresch is not the same, neither are the terrorists. They and their followers may believe something to be true, but theirs is a belief on faith alone. The apostles had the evidence to back up their believes and likewise, if it never happened had the eveidence to know that their believes were wrong. What you have is evidence of men who either went to their deaths knowing because they never saw the ressurected Jesus that they were preaching a lie or they went to their deaths preaching what they knew from their eyewitness evidence was the truth. It is clearly more logical to assume that they went to their deaths preaching the truth.
And you can't say with any degree of logic that all of these men were mentally delusional. Jesus appeared to numerous men who than were killed for their believes. The available evidence is that these men acted normal in all other aspects of their lives and there is no evidence that they were mentally insane. Also, the belief that all of them would be so insane is not very probable.
So Christianity is based upon the preaching of numerous individuals who preached that they saw and talked to the risen Lord and than went to their deaths for this knowledge. Logic does not support the thought that Christianity is based upon the preaching of numerous men who went to their deaths with the knowledge that what they were preaching was a lie or a hoax.
