Granted I do believe GOD does in fact allow us the rulers we as a people or rather we as a nation as a whole deserve. Governments can be ran by tyrants of by wise benevolent leaders. That choice is based on the hearts of the people.
I also believe when GOD see it as His will leaders should fall nothing will stop it nor if He wishes them to rise for His will for reward or punishment nothing will stop it but changed hearts. We should never stop speaking out against even in our leaders nor be silent of their wrongs especially when they act in a manner against GOD's Word.
If GOD wants leaders of nations or people gone GOD can make them such. Just look at Herod as one of the later examples in the Bible. Specific men in the Bible knew and understood that their people were enslaved or exiled by the Will Of GOD for a time. Among such was Jacob, Daniel, and to a certain extent King David who as you'll recall survived several attempts by Saul to kill him as a youth before he took Saul's place. It was not David who killed Saul though as he refused to do so as he stated Saul as GOD's anointed leader which even the Bible says as much.
Sin has already been judged at the Cross, but judgment of good and evil has not yet been concluded.
(This is one reason why sins may be forgiven in an instant, upon our facing Him through faith in Christ and confessing them to Him, while the consequences of good and evil are still to be resolved in time, but rarely in a split second as the issues of sin may be resolved in a moment’s notice.)
There remain many an issue being evaluated in the angelic domain, upon which human testing manifests His righteousness and justice.
For this reason, adversity is inevitable, in life and in death, but stress is optional through faith in Christ.
