It's not God's will that happened last night, it's our (as in the nation) will.
The following is my opinion, take it for what it's worth. Read 1 Samuel chapter 8. The people went to Samuel and demanded a king to rule them. Samuel was distraught, he tried to warn them, but they persisted. They didn't want God as their king, so God gave them what they asked for.
That is what we saw yesterday. Yes, many of us prayed, many are angry, scared and questioning why God would allow this. In the end God allowed the people to have what the majority wanted. History might say that we (the country) got what we deserve. We as a nation, rejected God, just as ancient Israel did. And just like ancient Israel, God has not, and will not, abandon us, even though we - as a nation - have abandoned Him.
It is very hard right now to come starkly face-to-face with the idea that all true Christians are going to suffer, and suffer terribly for their faith.
Yes, it is difficult to accept that. And yes, the future looks bleak. Go ahead and scream and yell at God if you have to. He can take it. When you are ready take out the 22nd psalm and read it - not just the first line that you cited but all of it.
We are being asked to keep a light burning in the darkness. It won't be easy. But it must be done.
