62 The present Encyclical has looked at the past, but above all it is directed to the future. Like Rerum novarum, it comes almost at the threshold of a new century, and its intention, with God's help, is to prepare for that moment. In every age the true and perennial "newness of things" comes from the infinite power of God, who says: "Behold, I make all things new" (Rev 21:5). These words refer to the fulfilment of history, when Christ "delivers the Kingdom to God the Father ... that God may be everything to everyone" (1 Cor 15:24,28). But the Christian well knows that the newness which we await in its fullness at the Lord's second coming has been present since the creation of the world, and in a special way since the time when God became man in Jesus Christ and brought about a "new creation" with him and through him (2 Cor 5:17; Gal 6:15). In concluding this Encyclical I again give thanks to Almighty God, who has granted his Church the light and strength to accompany humanity on its earthly journey towards its eternal destiny. In the third Millennium too, the Church will be faithful in making man's way her own, knowing that she does not walk alone, but with Christ her Lord. It is Christ who made man's way his own, and who guides him, even when he is unaware of it. Mary, the Mother of the Redeemer, constantly remained beside Christ in his journey towards the human family and in its midst, and she goes before the Church on the pilgrimage of faith. May her maternal intercession accompany humanity towards the next Millennium, in fidelity to him who "is the same yesterday and today and for ever" (cf. Heb 13:8), Jesus Christ our Lord, in whose name I cordially impart my blessing to all. Given in Rome, at Saint Peter's, on 1 May, the Memorial of Saint Joseph the Worker, in the year 1991, the thirteenth of my Pontificate.
