the ultimate psychology book

I was talking to somebody today and they made the statement that I found interesting. They said that the Bible is the ultimate psychology book. After thinking for a bit I realized that it really is. It tells about people doing bad things and making the same excuses that we do (ie. Cain and Able). There's references as to why people do certain things, unfortunately I can't find any specific references at the moment. People then struggled/delt with the same things as we do now (such as temptation, sin, doubt, greed). People act the same now as they did 3000 years ago, proving that the Bible has stuff to say about a bunch of people in the post-modern culture of 2009.
