You can find it here:
The entire Christian life is a response to God’s love. The first response is precisely faith as the acceptance, filled with wonder and gratitude, of the unprecedented divine initiative that precedes us and summons us. And the “yes” of faith marks the beginning of a radiant story of friendship with the Lord, which fills and gives full meaning to our whole life. But it is not enough for God that we simply accept his gratuitous love. Not only does he love us, but he wants to draw us to himself, to transform us in such a profound way as to bring us to say with Saint Paul: “it is no longer I who live, but Christ who lives in me” (cf. Gal 2:20).
When we make room for the love of God, then we become like him, sharing in his own charity. If we open ourselves to his love, we allow him to live in us and to bring us to love with him, in him and like him; only then does our faith become truly “active through love” (Gal 5:6); only then does he abide in us (cf. 1 Jn 4:12).
