He is allowing this for a reason... one we probably could not understand even if He told us.
Look at the nations and watch— and be utterly amazed. For I am going to do something in your days that you would not believe, even if you were told. Habakkuk 1:5
We must realize that God sets up authorities... which means He placed all the various leaders that are "in charge" in their places:
He changes times and seasons; He sets up kings and deposes them. He gives wisdom to the wise and knowledge to the discerning. Daniel 2:21
Everyone must submit himself to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. Romans 13:1
And they aren't quite as "in charge" as they think they are...
The king's heart is in the hand of the LORD; He directs it like a watercourse wherever He pleases. Proverbs 21:1
So what are we to do? What the Lord tells us to in 1 Timothy 2:1-2:
I urge, then, first of all, that requests, prayers, intercession and thanksgiving be made for everyone— for kings and all those in authority, that we may live peaceful and quiet lives in all godliness and holiness.
God is still God.... His plan continues to move forward unto completion.. we are to pray and be about His work... sharing the good news and glorifying Him in every thing we do!
