I'm not posting this to offend or to be "inflammatory" as some may see it. The factual historical reality of scripture is that we simply don't know its accuracy. The points he brings up are not opinion, just historical facts that you can either take from, or you can ignore them altogether.
I've been open about my skepticism when it comes to scripture being the inspired word of God. The truth is that this doesn't prove scripture wrong, but it does validate the skepticism I and others have when all the points are considered. These are not things the church on the corner will teach on Sunday mornings.
There's a video on YouTube of a debate between Bart Ehrman and Daniel Wallace on scriptural accuracy. It's far more indepth but also 2 hours long so I saw no reason to post it here. In that video, Ehrman shows pictures of our oldest scriptural text on a piece of tattered and torn paper. It was produced 150 years after Jesus' death, only contained 5 verses of Mark, and is itself a copy of a copy of a copy of a copy of a copy, etc. Yet someone had to fill in the many blanks to arrive at what our modern Bible says. There are too many points to list here so the video is worth watching to get the full effect. It's easy to find on YouTube.
I know many here will simply say these historical new testament scholars are just wrong. Yes, it's inconvenient to acknowledge these facts if your identity is wrapped up in religion. You'll no doubt defend whatever belief system you have chosen so there's no need to get defensive because I get it.
For those who believe God doesn't require robotically closed minds these are worth watching.
