We must decide how to save God’s creation from a changing climate that threatens to destroy it. We must seek peace at a time when there are those who will stop at nothing to do us harm, and when weapons in the hands of a few can destroy the many. And we must find a way to reconcile our ever-shrinking world with its ever-growing diversity – diversity of thought, of culture, and of belief. In short, we must find a way to live together as one human family.
