In reading this book, we cannot forget that one of the main goals of the author is to exalt Jesus Christ and to show how He is the fulfillment of God's salvific promises.
In the first three verses of Chapter 1 we are given some important information: First, we have a timeframe of events in that we are now in the last days. These days are not, as is often portrayed by those looking for an immediate return of Christ, merely the final days of the world as we know it, but the days that are taking place after the death and resurrection of Christ. We have been, are, and will remain to be in the last days. Second, the author tells us that the Son was active in Creation. Lastly, the Son is divine, the Son upholds all things providentially and the Son is the one who purged our sins and now sits in glory.
The rest of chapter 1 then goes on to show why the Son, jesus Christ, is elevated above all, divine, not merely just man, but the God-man.
The author then moves on to show how if the neglect of God's word in the past was met with punishment, so much more will be our judgment if we neglect the words of salvation given by the Son Himself. We are shown that the world to be will be governed not by angels but by man, and not just any man, but the Son. Despite the perceived tragedy in His death, the Son will rise again to take the throne, for his death was merely the means of deliverance for God's people. God is, and will, put all things into sujection to the Son. May we be one called part of the brethren(vs. 11) and not merely subjected as an enemy. Lastly, Jesus died to release us from the fear of bondage, to the devil, to our sin, to our fear of death, for none of these can hold sway over us anymore, although to those who do not believe we can rest assured that these fears remain. Let us rest in God's word knowing that for whatever reasons He has determined to aid the sons of Abraham in a way that even the angels are destitute of hope.
