Not because I agree completely (or even mostly) with what the speaker relates.  It's just interesting for the questions that it attempts to raise and answer.

The speaker, A.J. Jacobs, is a journalist as he tells us at the start of his talk.  If you're interested, the book which forms the basis for this talk is available on Amazon.  I haven't read it, but I just might, someday, though I suspect I have gotten much of the meaning from the book just in this short talk.

I thought that there were several interesting comments in this talk.  First, his brief treatment of how our behavior really does influence our thinking and emotions.  In other words, what we do changes who we are on the inside - for those who find some of the Old Testament's rules on how to live and dress confusing, this is a good thing to remember.  The external serves not just as a reminder but a conditioner for the internal.  Perhaps the author could have remembered this a bit more as he talks about not denying the irrational towards the 14:30 mark in the video.  Just because it doesn't make sense right away, doesn't mean it doesn't have a very good purpose.

Throughout, the author definitely demonstrates that he's using his 20th century agnostic understanding of the world to judge the Bible and determine (as he talks about at the 16:00 mark) what to follow and what not to.  Assuming that it isn't God's inspired Word (9:30), changes the very nature of  what it says and how one responds to it.  It allows one to judge areas that you don't agree with as 'barbaric' (9:00), and others as wise.  It determines what you decide can be taken literally and what can't (9:45).  It affects what you're willing to believe (10:50).  

Yet it was nice to see that Jacobs experienced quite a few pleasant surprises in this endeavor that is obviously meant as tongue-in-cheek, and ultimately a repudiation of what the Bible says precisely because it seems so irrational.  He learned the benefit of being thankful (11:15), though he probably didn't and doesn't have any idea of who to be thankful to.  He still found himself focused on all the good things that happen each day rather than the few bad things.  He learned the value of being a "reverent agnostic", (12:10), and not denigrating the idea of the divine or sacred, even if you yourself are not certain you believe these things exist.  He learned firsthand, as a workaholic, the benefits of keeping the Sabbath.  And in this, I suspect that he experienced the blessings of the Sabbath far more as God intended them than most church-going Christians do.  He learned that stereotyping Christians is misleading (13:30), and that just because you don't understand something doesn't mean that it has no meaning or purpose or value (14:30).  

His conclusion is one based on his lack of understanding in how to approach the Bible.  He concludes that you have to pick and choose what to follow (16:00).  So he would prefer to choose to follow passages about love and compassion, and ignore passages with difficult things to say about how we treat one another (sexual laws, punitive directives, etc.).  If he could have understood that much of the minute regulations of the Old Testament (according to Christians) were for a particular place and time (the theocracy of Israel, which formally ended in 70AD with the final destruction of the Temple and the Diaspora), while the larger issues that those specific directives dealt with remain valid, he might have found it less confusing.  He might have been able to see that while we aren't to stone people to death today, the actions that would have earned them stoning 2500 years ago are still equally problematic and dangerous today, both to them as an individual as well as to human community on a larger scale.  

I commend Jacobs for wanting to take the Bible seriously on one level, though he was clearly not equipped to really do so.  If he had believed that the Bible was more than just the arbitrary (or intentional) edits and changes and tweaks of generations of people (9:30), he probably would have been better able to take more seriously the goals of some of the Levitical laws.  He would have better understood the relationship which the Bible assumes - that we are Creations who need guidance in how to live our lives.  

I wish more Christians (myself included!) took more seriously the idea that we really need to live out our faith in tangible, expressible ways, some of which are inconvenient and frustrating.
