Chapter 10 completes the long, detailed explanation of why **the new covenant is superior to the old covenant**. Starting in chapter 7, the writer gave various arguments and Scriptures to support this idea. The theme of these points is that God had always intended to send Jesus, as the real fulfillment of the old covenant's symbolism. The second half of this chapter transitions into more practical ideas, including an extremely dire warning about the dangers of apostasy (BibleRef).
