None of this refutes the way I interpreted the scripture in my last post. My conclusions were based on exegetical analysis of the verse not on broad opinions about the issues. The scripture I quoted reveals that though God has the authority to bring the nations under subjection to His will He has chosen, for the time being, at least, to forbear.
He will take active control over the nations only when the seventh trumpet sounds and the voices from heaven proclaim:
“The kingdoms of this world have become the kingdoms of our Lord and of his Christ, and he shall reign forever and ever.” (Revelation 11:15)
24 Then the end will come, when He hands over the kingdom to God the Father after He has destroyed all dominion, authority, and power. 25 For He must reign until He has put all His enemies under His feet. (1 Corinthians 15:25)
Until then, the nations are ruled by men, many of whom serve the Wicked One. God reigns in His kingdom but He has not yet put all His enemies under His feet.
When God subjected all things to him, He left nothing outside of his control. Yet at present we do not see everything subject to him. 9 But we see Jesus, who was made a little lower than the angels, now crowned with glory and honor because He suffered death, so that by the grace of God He might taste death for everyone (Hebrews 2:9).
There is a difference between what God can do or WILL do in the future and what He chooses to do now. Though He has all authority He will not exercise that authority until Christ returns which is why, in the present, we "do not see everything subject to Him" Calvin might say God is already in complete control of the governments of the earth. These scriptures deny this idea.
But we need not consult arcane theological books to see that man is not in obedience to God's will. The writer of Hebrews says, "we do not SEE everything under His feet." The world's rebellion against God is something anyone can SEE. However, going by what you have said so far, if God does not actively control everything then He is not definition "sovereign" but is "limited." Does the fact that He has not taken control of the nations make Him "limited?" Does God not have the right to refrain from controlling people until the cup of wrath is full? It is evident that God has generally chosen not to restrain the acts of mankind even though they are contrary to His will. As the sovereign Lord He has the right to make such decisions.
