Another thing to take into consideration, especially when trying to use the Bible as a source of reference, is that there is not one shred of corroborating evidence that Jesus, or at least the Jesus as described in the Bible, ever existed. Which to any reasonable person should come across as odd, considering all the attributes and activities that are credited to him in the NT. While the Bible tells of great crowds that gathered to hear him speak, to be healed, or just to catch a glimpse of him, actual contemporary historical records are completely silent concerning him. Wouldn't you think that if he was actually living and moving around the area, which was under Roman rule, that some scribe or historian would have noticed and written it down? After all, the Romans were notorious record keepers. They recorded everything. The gospels themselves have been shown to have been written no less than 40 years after Jesus was supposed to have lived. And forget about Josephus Flavius. Not only has the two mentions in his works been shown to be forgeries inserted into his records, but he wasn't even born until approximately 5 years after the alleged crucifixion of Jesus. Therefore, he couldn't possibly have been a witness to Jesus, so even if the mentions of him in Josephus' writings were not forgeries, the best they could be would be hearsay, which is not credible evidence.
Even events that weren't actually initiated by Jesus but were tied to him, such as the graveyards opening up and the dead walking at his resurrection, are never mentioned anywhere outside of the gospels. And many times, these occurrences are only mentioned in one gospel while being ignored in the others.
As Kali and Sigmaleph have stated, using the Bible as proof of God is meaningless unless a person is already predisposed to believe that way already. Someone such as myself that grew up in a Christian home and attended church for 33 years only to leave the "faith," will not be so easily persuaded and will require a substantial amount of irrefutable proof to once again belief that, not only the Christian god, but any god(s), exists.
