For He has not subjected to angels the world to come that we are talking about. But one has somewhere testified:
What is man that You remember him,
or the son of man that You care for him?
You made him lower than the angels
for a short time;
You crowned him with glory and honor
and subjected everything under his feet.
For in subjecting everything to him, He left nothing that is not subject to him. As it is, we do not yet see everything subjected to him. But we do see Jesus—made lower than the angels for a short time so that by God’s grace He might taste death for everyone—crowned with glory and honor because of His suffering in death.
For in bringing many sons to glory, it was entirely appropriate that God—all things exist for Him and through Him—should make the source of their salvation perfect through sufferings. For the One who sanctifies and those who are sanctified all have one Father. That is why Jesus is not ashamed to call them brothers, saying:
I will proclaim Your name to My brothers;
I will sing hymns to You in the congregation.
Again, I will trust in Him. And again, Here I am with the children God gave Me.
Now since the children have flesh and blood in common, Jesus also shared in these, so that through His death He might destroy the one holding the power of death—that is, the Devil — and free those who were held in slavery all their lives by the fear of death. For it is clear that He does not reach out to help angels, but to help Abraham’s offspring. Therefore, He had to be like His brothers in every way, so that He could become a merciful and faithful high priest in service to God, to make propitiation for the sins of the people. For since He Himself was tested and has suffered, He is able to help those who are tested. – Hebrews 2:5-18 (HCSB)
As if anticipating the historical development of the 4th century, our author proceeds from establishing the divinity of Christ, to demonstrating his humanity.
The author here is expounding on the already-not-yet nature of post-resurrection reality. The Psalm he cites prophesies that son of Man would have all creation subjected to him, but our author comments that as of right now we do not see that to be the case. However, he notes, the fulfillment of this prophecy is ongoing in that the Lord was incarnate (made lower than the angels). The purpose of this, so says our author, is that by the covenant grace of the Father, the Son might taste death on behalf of his people, and because of that suffering we might all be crowned with glory and honor.
This section can often be confusing if we don’t have a proper grasp of the Hypostatic Union and how it interacts with Soteriology. Space does not permit me to go into a full explanation, but the abbreviated version is this:
What Christ had by nature (A filial relationship with the Father and all the blessings that entails), he also had to obtain by means of obedience and suffering according to his human nature. Once he obtained this relationship as a man, he graciously gives it to all those who are united with him by faith.
That is why our author can say that the Son (who was eternally perfect) was made perfect through suffering.
The text goes further to demonstrate that it is this filial relationship that the Son possessed by nature and merited by obedience, he gives to us by grace by stating that not does the one who sanctifies (the Son) but also we who are sanctified have God as our Father.
What a joy it is to say that God is our Father. How mysterious and humbling this great blessing is!
Furthermore, not only can we claim God as our Father, but we can claim Jesus as our Brother. He is not ashamed of us, and as we saw in the first chapter, he came to speak the Father’s word to us.
Because of the filial relationship the Father desired to have with his people, the Son had to take on our nature. This sharing in our nature was not only proper, but necessary.
Finally, we see that the taking on of our nature was not partial, but complete. He became like us in every way (except sin… which is an alien intruder into our true nature) in order to redeem us. It is because of this that he can help us.
