Currently, while we see human governments controlled by humans, strictly speaking, our present world (like it or not) is controlled or subject to “angelic powers”, the “god of this world” as in, 2 Corinthians 4:4, “Satan, who is the god of this world, has blinded the minds of those who don’t believe. They are unable to see the glorious light of the Good News. They don’t understand this message about the glory of Christ, who is the exact likeness of God.”(Living Translation).
But in Hebrews 2:5, the future world’s “executive powers” will not be with angelic being like Satan, as in “And furthermore, it is not angels ( even Satan) who will control the future world we are talking about.”(New Living Translation).

The truth is, and one can bank on this, that the future world will not be subjected (again) to angels. This is why “humans” need to change into “sons of God” by adoption into the “God-kingdom”. Sons of God are immortal and of higher category than angelic spirit-beings. This is the destiny of humans to be “sons of God”
