A psalmist wrote a song in a time of social dislocation, probably war. But those who can stay and fight for justice, must do that. And he reminds himself that the Lord his God is still reigning, despite appearances to the contrary. Look around, and you will experience fear. Look up, and faith will carry you through.
Human events are transitory, viewed from the long perspective.
The most radical thing you can do when things are very bad is to pray, says Jacques Ellul. We mix works and prayer with faith, and work for change. As the old mystic put it, if you have God and everything else, you have no more than having God only. God is working his purpose out as year succeeds to year and the earth will be filled with the glory of God as the waters cover the sea. A good, and a hard question.
