Though David wrote Psalm 8 about man as in mankind, the author of Hebrews also recognized a unique application for the God-Man, Jesus Christ.
For it was not to angels that God subjected the world to come, of which we are speaking. It has been testified somewhere,
“What is man, that you are mindful of him,
or the son of man, that you care for him?
You made him for a little while lower than the angels;
you have crowned him with glory and honor,
putting everything in subjection under his feet.”
Now in putting everything in subjection to him, he left nothing outside his control. At present, we do not yet see everything in subjection to him. But we see him who for a little while was made lower than the angels, namely Jesus, crowned with glory and honor because of the suffering of death, so that by the grace of God he might taste death for everyone. (Hebrews 2:5–9)
God gave man dominion on earth, but God gave His Son dominion over the dominion-takers, the history-makers, and even over the nay-sayers. “At present we do not see everything in subjection to him.” Sinners still live and sin and stand against the Son of Man. Men still reject their Creator and suppress the truth they know about Him.
We have not reached the final chapter, but we will see all things in subjection, we will see God’s will on earth as it is in heaven, because Christ’s dominion is not potential. It is established; He is risen from the dead.
All things, including governments and businesses and neighborhoods, will be in service to the Son because He already suffered, died, and rose again. He did it as grace. He did it as a substitute. He did it to redeem “many sons” and bring them to glory through sanctification (Hebrews 2:10).
He is helping the tempted now (Hebrews 2:17-18). He is changing us now. He is identifying with us, unashamed to call us brothers now (Hebrews 2:11), even as He invites us to eat His flesh and drink His blood.
At present we do not see everything subjected to Him. But the world ought to see us in subjection to Him as we gather at His Table.
