Hi Prudence,
I agree with what you say here about faith vs fact. My post was a way of saying "if the factuality of Jesus, resurrection, etc, is so key to Christianity, why did God do such a poor job of factualizing it?" I agree it's a slippery slope -- you can never provide some people all the evidence they want -- at some point you just have to choose to believe on faith, or walk away.
The thing I'm working on is, in large measure, an answer to (as you ask) "is there is any possible method to make knowledge conclusive?" I've actually made big progress. I think I've written 90% of it, but now it is 12 pages, and I need to weed out the digressions and get it to flow better.
