This chapter contains the thesis statement for the whole book: God has spoken through his Son! Jesus is the exact representation of the essence of God. No wonder people either stumble at or submit to Him! Jesus brought forth everything by the word of his power.
The rest of the chapter is a piling up of Hebrew Scriptures that speak of Christ. They tell us simply, Jesus is in a class by himself. God relates to Jesus differently than he does to angels. Jesus is greater than angels.
