I just finished reading this book by Peter Enns and it is fantastic. I highly recommend For the Bible Tells Me So to every Christian who thinks they know what the Bible “plainly says.” Enns directly tackles the purpose of the Bible. He even has some very interesting things to say about how the apostle Paul and even Jesus use the Hebrew Bible. You can currently purchase the book through my affiliate link on kindle for $1.99. If you prefer physical books, you can get it that way too.
