The first chapter of Hebrews establishes two primary ideas used to support the rest of the book. **Firstly**, that God has spoken to mankind, most recently through Jesus, so we ought to be listening to Him. **Secondly**, chapter 1 introduces the fact that Jesus is superior to other spiritual beings, such as angels. These concepts are used to support the superiority of faith in Christ, over the Old Testament Law, expressed in the book's later chapters (BibleRef).
