There are a variety of Bible inconsistencies. Some deal with things like conflicting accounts (numbers that do not match and the like) and some are more important. One that bothers me is the prophecy of Isaiah 7:14. Christians claim this is a prophecy about Jesus and the Gospel according to Matthew states that Isaiah 7:14 is about Jesus. However, a clear reading of the passage (Isaiah 7:14) makes it very clear that Isaiah never had the birth of Jesus in mind. Here is a link dealing with the passage:

And, yes, I wrote that (before Smitty tries to say I was hiding that fact).
