Journey Twelve begins with the best known and most beloved book of the prophets. Jesus quotes Isaiah more than any other book, and scholars call it "the fifth gospel" because of its rich Messianic prophecies. In the New Testament, Galatians teaches us the difference between the fake gospel and authentic Christianity. Finally, 1st Corinthians delivers practical correction for an out-of-line church, and reminds us what following Jesus is all about.
