Fiend God
I find the last point most interesting. The desciples stayed true to their beliefs despite persecution and the threat of death. Athiests have difficulty in explaining that away.
No, they don't. Tons of people die for their beliefs. It doesn't make them true, otherwise lots of otherwise mutually-exclusive religions would be true simultaneously.
Why did they not cave-in and go back to their old ways? Because they were totally convinced the Resurrection had taken place.
Indeed, and that's the only conclusion you can come to.
