Want to know more? Michael Kruger is an expert on the Bible and the Biblical Canon. Watch a few of his videos (even the short interviews) and you'll know more about how we arrived at the Bible we have today than most folks you know. He is a great source of information.

Want to know even more? The same guys has a blog which is full of amazing articles and takes on not only Canon, but theology and Christianity in general.

These books I highly recommend. Evidence is simply a great reference for pretty much all of Christianity. Every Christian should read "How we got the Bible" for both its ease of relating the material and for the immense amount of information it relays. Kruger's book is a bit deeper, but worth the time if you want to understand why we trust the Scripture so completely.
