I'm sorry you think I'm a nut. My belief is belief, yes. But its also grounded on logic and reasonability. As well as evidence from the Bible. I know it appears to be illogical in that I'm trying to argue from within a particular system of belief instead of arguing from outside the system to attempt to prove my point. But it actually is more logically correct to argue from the standpoint of internal consistency given that I actually do believe that God is really capable of total sovereignty. There is certainly more evidence than just the Bible to corroborate the existence of Jesus and his actions (Josephus, archeological clues, even the Koran). But because I believe that God is really capable of proving His own existence I rely most on the Bible to describe the truth.
As to your particular points/questions.
1)"how do we know which version of the Bible is his word?"
The version that most closely approximates the earliest manuscripts that most consistently agree. As far as English translations go, most scholars would agree that its either New American Standard Bible (NASB) or the English Standard Version (ESV). It turns out that there really aren't that many inconsistencies amongst the different copies we have access to now-a-days. Most of the differences are things like "the Lord Jesus Christ" vs. "Jesus Christ the Lord" it counts as a difference, but its really not meaningfully different. If you're serious about examining this topic, and I hope you are, take a listen to this
presentation by Dr. Dan Wallace. It's excellent. Very academic from one of the world's leading scholars.
2)"You have just as much evidence the fairy exists as you do god."
Actually the main reason I believe in God is because there is an empty tomb where the body of Jesus was initially laid. Its empty because He rose from the dead which sort of serves as a receipt of payment for our sins, thus satisfying God's righteous wrath against those sins. Now if you're going to try and make the "the disciples stole the body" argument, I'm sad to say that the evidence is quite stacked against that one. (1) they were a rag-tag group of laborers who were dispersed and scared when their leader was killed and had no ability or courage to try and 'rescue his body' (2) The body was buried in a tomb with a huge rock rolled down hill, sealed by the Roman seal, and guarded by a bunch of Roman soldiers. See point 1, there's no way they were going to move the stone, break the seal, and defeat a bunch of guards.
Matthew 27:57-64 describes all of this.
I hope that answers some of your questions. Please feel free to continue this thread if you want to discuss things further.
