The book of Hebrews compares and contrasts Jesus to key historical people and events from the Old Testament. Through these comparisons, we see His superiority. He is greater than angels, the Torah, Moses, the Promised Land, priests, Melchizedek, sacrifices, and the covenant. He is God's Word, the hope for a new creation, our eternal priest, and the perfect sacrifice.
Throughout the book, we are also challenged to remain faithful to Jesus and follow great models of faith from the Old Testament despite hardships and persecution. These challenges will make us uncomfortable but instead of fearing them, remember that rejecting Jesus is foolish.
Jesus is the ultimate revelation of God's love and mercy and is worthy of all our trust and devotion.
