The book of Hebrews is a deep study into the way in which the people in the Old Testament showed faith in Jesus before He was revealed. Although the author is not known for certain, the writer of Hebrews is very well versed in Israelite history, and this letter is full of references to various Old Testament books. Readers are walked through comparisons of Christ to angels, to Moses, to high priests, and the primary message is clear throughout each example: Jesus is supreme, superior, and sufficient for salvation. After the long discourse of proving the greatness of the Messiah, the book ends with practical applications of understanding our faith and how we relate to God and to His Church. The writer encourages us and teaches us how to persevere amidst the troubles found in this world as we keep our eyes on the One who is in control of it all.
