Bruce Waltke, An Old Testament Theology

I'm slowly working my way through Bruce Waltke's, An Old Testament Theology. A few weeks ago I underlined these sentences from page 10:

The Bible explores and answers with authority the most fundamental issues facing human beings: Who are we? What is the world and our place in it? How can we find happiness in this conflicted world? How do we deal with choices that confront us, and what happens as a result? This is the stuff of great literature, and the Bible is the greatest expression of it.
