You are “planted and built up in Jesus Christ, firm in the faith” (cf. Col 2:7). The Letter from which these words are taken was written by Saint Paul in order to respond to a specific need of the Christians in the city of Colossae. That community was threatened by the influence of certain cultural trends that were turning the faithful away from the Gospel. Our own cultural context, dear young people, is not unlike that of the ancient Colossians. Indeed, there is a strong current of secularist thought that aims to make God marginal in the lives of people and society by proposing and attempting to create a “paradise” without him. Yet experience tells us that a world without God becomes a “hell”: filled with selfishness, broken families, hatred between individuals and nations, and a great deficit of love, joy and hope.
Experience shows that personal qualities and material goods are not enough to guarantee the hope which the human spirit is constantly seeking. As I wrote in the Encyclical Spe Salvi, politics, science, technology, economics and all other material resources are not of themselves sufficient to provide the great hope to which we all aspire. This hope “can only be God, who encompasses the whole of reality and who can bestow upon us what we, by ourselves, cannot attain” (no. 31).
“You will receive power when the Holy Spirit comes upon you” (Acts 1:8). We have seen this promise fulfilled! On the day of Pentecost, as we heard in the first reading, the Risen Lord, seated at the right hand of the Father, sent the Spirit upon the disciples gathered in the Upper Room. In the power of that Spirit, Peter and the Apostles went forth to preach the Gospel to the ends of the earth. In every age, and in every language, the Church throughout the world continues to proclaim the marvels of God and to call all nations and peoples to faith, hope and new life in Christ.
“You will receive power when the Holy Spirit has come upon you: and you will be my witnesses” (Acts 1:8). This is the theme of the Twenty-Third World Youth Day. How much our world needs a renewed outpouring of the Holy Spirit! There are still many who have not heard the Good News of Jesus Christ, while many others, for whatever reason, have not recognized in this Good News the saving truth that alone can satisfy the deepest longings of their hearts. The Psalmist prays: “when you send forth your Spirit, they are created, and you renew the face of the earth” (Ps 104:30).
