Faith, which sees the love of God revealed in the pierced heart of Jesus on the Cross, gives rise to love. Love is the light—and in the end, the only light—that can always illuminate a world grown dim and give us the courage needed to keep living and working. Love is possible, and we are able to practise it because we are created in the image of God. To experience love and in this way to cause the light of God to enter into the world—this is the invitation I would like to extend with the present Encyclical.
