"Moreover, our radical belonging to Christ and the fact that “we are in him” must imbue in us an attitude of total trust and immense joy. In short, we must indeed exclaim with St Paul: “If God is for us, who is against us?” (Rom 8: 31). And the reply is that nothing and no one “will be able to separate us from the love of God in Christ Jesus our Lord” (Rom 8: 39). Our Christian life, therefore, stands on the soundest and safest rock one can imagine. And from it we draw all our energy, precisely as the Apostle wrote: “I can do all things in him who strengthens me” (Phil 4: 13).
Therefore, let us face our life with its joys and sorrows supported by these great sentiments that Paul offers to us. By having an experience of them we will realize how true are the words the Apostle himself wrote: “I know whom I have believed, and I am sure that he is able to guard until that Day what has been entrusted to me”; in other words, until the Day (II Tm 1: 12) of our definitive meeting with Christ the Judge, Saviour of the world and our Saviour."

“Gaudete in Domino semper - Rejoice in the Lord always (Phil 4: 4).”
“Christian joy thus springs from this certainty: God is close, he is with me, he is with us, in joy and in sorrow, in sickness and in health, as a friend and faithful spouse. And this joy endures, even in trials, in suffering itself. It does not remain only on the surface; it dwells in the depths of the person who entrusts himself to God and trusts in him.”

“… there is one great Friend, who is the author of the joy of all and who fills our hearts with a joy that surpasses all other joys and lasts a lifetime: he is Jesus.”
