Think about the following passage, and let what it has to say soak in.
When I read this passage, it makes me think of God's plan for mankind. You see God didn't plan for us to be in subjection the world, but for the world to be under our authority. Many people think that the devil has more power than man, but in reality He only has what power we give him.
In the beginning, God said man would have dominion over the earth, and after Jesus resurrection, the Holy Spirit gives us back, through Jesus Christ, the authority and dominion we, as born again believers, once had while in the garden.
So "What is man that you are mindful of him?" Just God's crowning creation!
5 For He has not put the world to come, of which we speak, in subjection to angels. 6 But one testified in a certain place, saying:
“What is man that You are mindful of him,
Or the son of man that You take care of him?
7 You have made him a little lower than the angels;
You have crowned him with glory and honor,
And set him over the works of Your hands.
8 You have put all things in subjection under his feet.”
For in that He put all in subjection under him, He left nothing that is not put under him. But now we do not yet see all things put under him. 9 But we see Jesus, who was made a little lower than the angels, for the suffering of death crowned with glory and honor, that He, by the grace of God, might taste death for everyone.
