From Where is God? The Supremacy of Christ in an Age of Terror delivered by John Piper on September 11, 2005:
One of the truths of the Bible that we embrace with trembling joy is the truth of God’s supremacy in all things. The mission of our church is that we exist to spread a passion of the supremacy of God in all things for the joy of all peoples through Jesus Christ. When we say that, we do not mean: “except in calamities,” “except in war,” “except when Al Qaeda blows up a building or a train,” “except when cancer takes a mom or a child is born with profound disabilities.” There are no “except” clauses in our mission statement (emphasis mine).
We did not formulate our mission in a rosy world—and then get surprised and embarrassed by the reality of suffering. We did not have our head in the sand. We formulated our mission in the real world of pain and suffering and evil and death. We have seen even among our own people, some very peaceful, but also some very terrible deaths. We exist to spread a passion for the supremacy of God in all things—all things—for the joy of all peoples through Jesus Christ—all the time. A passion for God’s supremacy—Christ’s supremacy (for he is God incarnate)—in all things, all the time.
Pastor John ends this sermon answering this question: “Why, Lord? Why is the world you made like this? If you are God—if you are the Christ the Son of the living God—why is this world so full of terror and trouble?”
Whether you know the answer already or not, it was a great comfort to me! I encourage you to watch or read this sermon.
