God's Sovereignty Encompasses Everything

How can we really say God is sovereign over all when there is so much chaos and pain in the world?

Nothing shall hinder his great design. God's great ends will be obtained: all his ends will be obtained, and by his own means.

After all this seeming confusion and vast succession of strange and wonderful revolutions, everything shall come out right at last. There is no confusion in God's scheme; he understands his own works and every wheel moves right in its place.

Not one mote of dust errs from the path that God has appointed it; he will bring order at last out of confusion. God don't lose himself in the intricate endless moves of events that come to pass. Though men can't see the whole scheme, God sees. The course and series of events in divine providence is like the course of a great and long river with many branches and innumerable windings and turnings which often seems to go backwards. 

--Jonathan Edwards, 1744 sermon entitled "Approaching the End of God's Grand Design," in Works, 25:121
