Like most anyone with a brain who also walks a path of spiritual or religious faith, I have my moments of doubt.
But when I do, the thing that always brings me back to Jesus is this: To me, the actions and behaviors of the apostles (the original ones [sans Judas Iscariot] plus the replacement guy, plus Paul, who is a special late-addition case), make no sense whatsoever unless Jesus lived, proved to them his divine nature, died, and rose from the dead definitively.
For them to have such uniformity of action, commitment to an executed man, and put themselves to the kind of risk they did, all to establish the early Christian church, makes no sense otherwise. It defies human nature, self-interest, and self-presevation for all 13 of those people, one of whom had a position of authority before converting to Jesus’ path, to do that. And to stick with it even through persecution and unto their very deaths as martyrs.
So, to those of you who want to knock me off my faith, you are going to have to give me credible reason to believe that Jesus never even existed, and neither did the apostles, for you to knock me off my faith.
Consider it a challenge if you like. If you can provide me with such such evidence of those two assertions that it overwhelms the record of the existing sources from which I currently draw my knowledge and on which I base my faith (and that comes from historical sources, not just biblical ones), then I will publicly declare myself agnostic.
Disprove the existence of those people, and I will admit that my faith is fundamentally flawed.
