It is well to remember that the dignity of work is based on Love. Man's great privilege is to be able to love and to transcend what is fleeting and ephemeral. He can love other creatures, pronounce an "I" and a "you" which are full of meaning. And he can love God, who opens heaven's gates to us, makes us members of his family and allows us also to talk to him in friendship, face to face.
This is why man ought not to limit himself to material production. Work is born of love; it is a manifestation of love and is directed toward love. We see the hand of God, not only in the wonders of nature, but also in our experience of work and effort. Work thus becomes prayer and thanksgiving, because we know we are placed on earth by God, that we are loved by him and made heirs to his promises. We have been rightly told, "In eating, in drinking, in all that you do, do everything for God's glory."
