Jesus is: greater than angels (chaps. 1–2); greater than Moses (3:1–4:12); greater than the priests and high priests (4:13–7:28); and greater than the Old Testament sacrifices (chaps. 8–10).
Since this is so, like those heroes of the faith who looked forward to the Messiah’s coming, we need to: keep our eyes glued to Him as we persevere in faith (chaps. 11–12) and live together as the new covenant community (chap. 13).
If we get lost in the details, Hebrews will appear to be a long, maze-like book. But if we grasp the big picture, we will see why the author thought he had “written … only a short letter” (13:22, NIV).
