Heb. 1; 2 Before presenting Christ in service founded on His person, chapter 1 not simply gives the natures to which the respective services belonged, but presents His personal glory and place—what He is, not what He does for others. In order to this last, it states His divine and human nature; but before this, as I said, His place. God now spoke (ἐν υἱῷ) in [the person of the] Son. He is at the beginning of all creature existence as Creator, at the head of it as Heir of all things. Then, as between God and man, He reveals God, the brightness of His glory and express image of His being. He continuously upholds all things; and this, in a divine way, gives man his place with God. By Himself He purged our sins and sat down at the right hand of the Majesty in the heavens—His own place, and His mediatorial place. It resembles Col. 1 in each part.
In chapter 2 we have Psa. 8 fulfilled as to the glorifying Christ, but not having all things put under His feet; but this the fruit of sufferings and death, so that as to title through righteousness God could bring sons to glory, and the power of Satan over them was destroyed. And while in the place of glorified Priest on high, where He has entitled us to enter, and where we as worshippers belong, He has passed through all the sorrows and temptations of the way so as to be perfectly suited in grace to our trials in the same path.
