“The Kingdom of God is a gift, and precisely because of this, it is great and beautiful, and constitutes the response to our hope. And we cannot—to use the classical expression—”merit” Heaven through our works. Heaven is always more than we could merit, just as being loved is never something “merited”, but always a gift. However, even when we are fully aware that Heaven far exceeds what we can merit, it will always be true that our behaviour is not indifferent before God and therefore is not indifferent for the unfolding of history. We can open ourselves and the world and allow God to enter: we can open ourselves to truth, to love, to what is good. This is what the saints did, those who, as “God’s fellow workers”, contributed to the world’s salvation (cf. 1 Cor 3:9; 1 Th 3:2). We can free our life and the world from the poisons and contaminations that could destroy the present and the future. We can uncover the sources of creation and keep them unsullied, and in this way we can make a right use of creation, which comes to us as a gift, according to its intrinsic requirements and ultimate purpose. This makes sense even if outwardly we achieve nothing or seem powerless in the face of overwhelming hostile forces. So on the one hand, our actions engender hope for us and for others; but at the same time, it is the great hope based upon God’s promises that gives us courage and directs our action in good times and bad” (Pope Benedict XVI, Encyclical Letter, Spe Salvi; emphasis mine).
