Government is instituted by God but there are authorities that do what’s right and those who are corrupt and do evil. There is nothing new under the sun. There were ungodly governments in history as there is now. So Governing authorities are there so that the rule of law is upheld and that evil is punished. They are to enact laws to punish the bad. It explains this in the Bible in 1 Timothy 1:8-10. Also check out Romans 13:1-7 to see the purpose of Government and that the leaders in a community, in a nation are ministers of God.
Proverbs 14:34 says,’Righteousness exalts a nation, but sin is a reproach to any people.’ Proverbs 11:10-11 says,’When it goes well with the righteous, the city rejoices; And when the wicked perish, there is jubilation. By the blessing of the upright the city is exalted, But it is overthrown by the mouth of the wicked.’ We should hold Government and leaders to the role that is given to them. There is good governments and corrupt governments. There is this pattern you see throughout history of people becoming leaders of nation but rather than seeing it as their duty to serve the people they represent, they use and abuse that office to become more powerful and to see their own selfish ambitions fulfilled. Throughout history we see leaders of nations and empires rise and fall but thank God that one day His Kingdom will be ruling and reigning on the earth. A perfect government. Daniel chapter 2 talks about kingdoms rising and falling as we can see in history but then in verse 44 it says,’And in the days of these kings the God of heaven will set up a kingdom which shall never be destroyed; and the kingdom shall not be left to other people; it shall break in pieces and consume all these kingdoms, and it shall stand forever.’
Revelation 11:15 says ‘Then the seventh angel sounded: And there were loud voices in heaven, saying, “The kingdoms of this world have become the kingdoms of our Lord and of His Christ, and He shall reign forever and ever!” Proverbs 16:12 says ‘It is an abomination for kings to commit wickedness, for a throne is established by righteousness.’
Also we see throughout history power being concentrated in the hands of one individual with dictators and oppressive governments. Let me mention a couple of books on this theme both by historian William J. Federer. The first one is Volume 1 Change to Chains-The 6,000 Year Quest for Control and Volume 2 Rise of the Tyrant.
