It's the third book of the Bible, called The Final Testament of the Holy Bible. My idea of what the Messiah would be like if he were walking the streets of New York today. What would he believe? What would he preach? How would he live? With who?
The ultimate goal of theology isn't knowledge, but worship. If our learning and knowledge of God do not lead to the joyful praise of God, we have failed. We learn only that we might laud, which is to say that theology without doxology is idolatry. The only theology worth studying is a theology that can be sung!
