The Holy Father wraps up his letter:
15. Having reached the end of his life, Saint Paul asks his disciple Timothy to “aim at faith” (2 Tim 2:22) with the same constancy as when he was a boy (cf. 2 Tim 3:15). We hear this invitation directed to each of us, that none of us grow lazy in the faith. It is the lifelong companion that makes it possible to perceive, ever anew, the marvels that God works for us. Intent on gathering the signs of the times in the present of history, faith commits every one of us to become a living sign of the presence of the Risen Lord in the world. What the world is in particular need of today is the credible witness of people enlightened in mind and heart by the word of the Lord, and capable of opening the hearts and minds of many to the desire for God and for true life, life without end.
We need enlightened and capable believers in the world: no argument here whatsoever.
“That the word of the Lord may speed on and triumph” (2 Th 3:1): may this Year of Faith make our relationship with Christ the Lord increasingly firm, since only in him is there the certitude for looking to the future and the guarantee of an authentic and lasting love. The words of Saint Peter shed one final ray of light on faith: “In this you rejoice, though now for a little while you may have to suffer various trials, so that the genuineness of your faith, more precious than gold which though perishable is tested by fire, may redound to praise and glory and honour at the revelation of Jesus Christ. Without having seen him you love him; though you do not now see him you believe in him and rejoice with unutterable and exalted joy. As the outcome of your faith you obtain the salvation of your souls” (1 Pet 1:6-9). The life of Christians knows the experience of joy as well as the experience of suffering. How many of the saints have lived in solitude! How many believers, even in our own day, are tested by God’s silence when they would rather hear his consoling voice! The trials of life, while helping us to understand the mystery of the Cross and to participate in the sufferings of Christ (cf. Col 1:24), are a prelude to the joy and hope to which faith leads: “when I am weak, then I am strong” (2 Cor 12:10). We believe with firm certitude that the Lord Jesus has conquered evil and death. With this sure confidence we entrust ourselves to him: he, present in our midst, overcomes the power of the evil one (cf. Lk 11:20); and the Church, the visible community of his mercy, abides in him as a sign of definitive reconciliation with the Father.
Let us entrust this time of grace to the Mother of God, proclaimed “blessed because she believed” (Lk 1:45).
