The commentary is excellent. For example, did you realize that Jesus began to teach in parables late in His ministry, and only after many people had turned against Him?
One other thing that I really like about this book is that every time an old testament prophecy is fulfilled in the new testament it gives the old testament reference right there in the text. I know that many Bibles note this, but they use superscript marks and it's easy to read over them, so I like the references in the reading, that way I don't miss anything.
