You will know more about Christianity than a lot of Christians.
It's definitely a good book if you are looking for common sense morality. I think the Jefferson Bible is a better book if you are looking for moral teachings (never read it, only heard about it)
On the Bible front, I'd recommend a story bible. There's a good reason so many people fail to read the Bible: it's full of motivational landmines such as genealogies. Even reading a story bible would put one far ahead in terms of understanding.
The one I read is the Ritchie pruehs story bible, which is free as a Kindle book.
