[...] Talking about God means first of all expressing clearly what God we must bring to the men and women of our time: not an abstract God, a hypothesis, but a real God, a God who exists, who has entered history and is present in history; the God of Jesus Christ as an answer to the fundamental question of the meaning of life and of how we should live. Consequently speaking of God demands familiarity with Jesus and his Gospel, it implies that we have a real, personal knowledge of God and a strong passion for his plan of salvation without succumbing to the temptation of success, but following God’s own method. God’s method is that of humility — God makes himself one of us — his method is brought about through the Incarnation in the simple house of Nazareth; through the Grotto of Bethlehem; through the Parable of the Mustard Seed.
We must not fear the humility of taking little steps, but trust in the leaven that penetrates the dough and slowly causes it to rise (cf. Mt 13:33). In talking about God, in the work of evangelization, under the guidance of the Holy Spirit, we must recover simplicity, we must return to the essence of the proclamation: the Good News of a God who is real and effective, a God who is concerned about us, a God-Love who makes himself close to us in Jesus Christ, until the Cross, and who in the Resurrection gives us hope and opens us to a life that has no end, eternal life, true life [...]
So it is that talking about God means making people realize through our speech and example, that God is no rival in our existence but rather is its true guarantor, who guarantees the greatness of the human person. Thus we return to the beginning: speaking of God is communicating what is essential, forcefully and simply, through our words and through our life: the God of Jesus Christ, that God who showed us a love so great that he took flesh, died and rose again for us: that God who asks us to follow him and to let ourselves be transformed by his immense love in order to renew our life and our relationships; that God who has given us the Church, so that we may walk together and, through the word and the sacraments, renew the entire city of men and women, so that it may become a City of God.
