In the third volume of his New Testament Devotional Commentaries Volume 3: Galatian Through Revelation, Bo Giertz returns to the text with his keen insight and love for God's word and God's people. This would finish his work as an author that began in the 1930s and continued for five decades.

Taking the principles of Biblical Realism he had learned from his mentor Anton Fridrichsen, with its rejection of both liberal higher criticism and fundamentalist biblicism, Bo Giertz opens some of the most difficult to understand texts in all of Scripture with a simple understanding that this is God's word for you. He blends this approach to Scripture with pastoral insight gained from his years as both a rural parish priest in the Swedish countryside and the Bishop of the bustling cosmopolitan center of Gothenburg. His commentary on Revelation is particularly revolutionary. Appendix: The Bible's View of Itself and Other Views of the Bible
