The importance of knowing each book of the Bible becomes obvious when we realize that God has given us each of the books so that we will know God. As we grow in our knowledge of Him we will grow spiritually. Consequently, studying the books of the Bible is the ultimate way to discover Him (Jeremiah 9:23-24). Doctrinal studies are important, but one's doctrine must always submit to the truth found in the Bible. May the Lord bless your study.
