"All Power from God. "God hath spoken once; twice have I heard this; that power belongeth unto God." Ps. 62:11.
This is absolutely true, without any exception. 
The Roman power, even in the days of the infamous and brutal Nero, was as much derived from God as was the Jewish power in the days of David.
When Pilate told Christ that he had power to crucify him or to let him go, Christ replied, "Thou couldest have no power at all against me, except it were given thee from above." John 19:11.
This fact does not, however, prove that the acts of that power were right, or that God sanctioned them.
It can as truly be said of every individual as of governments, that they are ordained, or appointed, of God. He has a plan for every one's life.
But that does not make God responsible for all their actions, because they are free to do as they choose, and they rebel against God's plan, and pervert his gifts.
---No man can be active in the affairs of two governments at the same time.
This applies to the government of heaven as related to earthly governments, as well as to different countries on earth.
---The one who is a citizen of the heavenly country has no business to meddle with the affairs of earthly governments. He must leave that business to those who acknowledge this earth to be their home."
E.J. Waggoner
