Upon reading this the first thing I noticed in chapter 1 was the fact that in these last days, because of what Christ did for us we have the ability to talk with God, and hear his messages. I personally think that is pretty awesome. And it would have had even greater meaning for the people this unknown writer was writing too. You see, in that time you could not talk to God and God could not talk to you. All communication had to go through a priest or prophet. These holy men were the only ones honored enough to be able to talk with God. But we are blessed enough that because of him sending his Son, Jesus Christ to us we can communicate with him, and bring our request before him. Without the bridge that Christ death created we would not be able to have the relationship with God as we do, but because of his great sacrifice we can.
Beyond that, as I went back and studied this chapter I found that in this culture and time, angles were exalted beings. They were especially revered because they had been involved in giving the law. Now to truly understand the implications of how important it was that theses angles gave the law you must understand that at this point, the only way you had a chance of staying in Gods good grace was by keeping the law. The ideas of Christís death hadnít really sunk in to them yet. So they revered them so greatly because they had a hand in what at the time was their only hope. But now they were given a greater hope; Jesus Christ.
But this passage stresses the fact that Christ is above the angles. He is the son of the Most High King, and because of him, we can talk to the Most High freely.
I think from a historical point this chapter is mainly to explain that Christ is above the angles, he is the one to be exalted and served. But from a strictly spiritual point itís to show us how great Jesus Christ is, that he is above even the angles, and yet he loved us enough to do the ultimate act of service to us by dying to allow us communication with the Lord, Created of heavens and earth.
