I personally disagree with the idea that a reasoned faith is impossible, or that blind faith is called for by the bible.
1. So many reasons for my faith I'm not sure where to start... Some may of course be inaccurate. I'm human and these are only observations. But overall I've reached the decision that it's more likely than not.
Awe of the numinous, the fact people even think about right or wrong, communication, the themes of blood as sacrifice and death to new life found in ancient religions, the prophecies in the old testament very specifically fulfilled in Jesus of Nazareth (not all poetry either

), the types of Jesus in the OT, the huge coherency of the bible despite the time span over which it was written and the different authors, outside texts yes (with an understanding of the bits likely added later), an historical consideration as to the validity of the texts and when they were written, if any changes occured or were likely after the text was produced, examining the gospel accounts and the book of Acts, and the claims of Christ (C.S. Lewis put it that he was either mad, a liar, or was what he cliamed - the Son of God), combined with his life and the lives of his disciples, the change in his discples after the resurrection. etc. etc. etc.
NTs: I do consider ideas for and against different aspects and the whole.
Note I don't think miracles in the gospels are a proof of their hisorical inaccuracy. They could be added later, lies ... etc. Or if it really was God involved there'd be no problem. Either viewpoint comes from a preconception. (There may be other explanations also, just using the most common).
2. In Acts, it's noted that the "Bereans were of more noble character than the Thessalonians, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true." (17:11) John's Gospel records Thomas asking for observable and physical proof that Jesus was alive - and he got it. Paul tells the Corinthians that many witnesses "are still living, though some have fallen asleep." (1 Corinthians 15:6).
I believe an earlier post mentioned that evolution will still be true even if people disbelieve in it. Yes, and the same is true of all reality. If a spiritual world exists, it does whether we believe it to or not. And vice-versa.
I do think that examination of the world and of history can point out some clues as to reality however. Of course, peoples opinions vary even if given the same raw data, and history isn't as clear cut as physical sciences.
