Cheermom,
To me, that is the beauty of it. God gives us freedom to choose what we want to believe.
Faith is believeing in things that you can't see. If God Himself came down to earth and told us...no wait, I believe that one happened

...uh, if God gave you the proof you wanted, would you then believe? And would that be knowing fact or having faith? I believe God gives us all lots of reasons to believe--we just brush them aside, do not accept them or want more evidence. That probably will not happen.
Yet, even as I say that, I think of how REAL God is to me in my life. Because of my personal experiences, He is fact for me. I have faith still but He is as real to me as anything or any person in my life right now. That is why I, and many other christians tend to to come off saying things like they are fact--to us, God could not be more real.
To me, if an "oops" happened and jesus was passed off as a baby who was the promised Messiah, I'd give it all up right this minute. If I could not believe that Mary was a virgin and Jesus was the Son of God and not Joseph's son, the rest would also be iffy for me and probably a made up lie.
Yet, between God's Holy Word, which I believe IS God inspired (why? because the Bible says so and it seems to me the men who wrote it down have been very careful with it + I think God is powerful enough to sustain His Word) and my personal experiences, I can never deny the presence of God. I think the the Bible tells us the things He wants us to know and it is given to us for a reason. It sure can be applied to life even in 2008, that's for sure!
Anyway, I think as long as you are pondering it, my belief is that God is still working with you on the subject. In the end, the choice is yours but I think it is wonderful that you are discerning for yourself and making a choice. Cause to me, it is all about personal choice (and personal relationship.)
