The Old Testament contains 12 comparatively short prophetic books perhaps unfortunately called the "Minor Prophets". Yet, as part of divine inspiration, they contain much prophetic truth, and as this book seeks to emphasize, much truth concerning the Lord Jesus. The Lord is going to be glorified - His excellence manifested on earth. He is going to be the supreme ruler of this earth, reigning in His kingdom glory for 1000 years. And we of the Church (and all of the first resurrection) will reign with Him (Rev. 20:4, 6). Therefore, these mostly short books should be important to us!
