Serving God and his mission is not a passing thing, but can and should be pursued in the present, with one's entire life, Pope Francis said Sunday at the closing Mass for World Youth Day in Panama City.

"Brothers and sisters, the Lord and his mission are not a 'meantime' in our life, something temporary; they are our life!" the pope said Jan. 27. "Not tomorrow but now, for wherever your treasure is, there will your heart also be."

Jesus "wants to be our treasure, because he is not a 'meantime,' an interval in life or a passing fad; he is generous love that invites us to entrust ourselves," he continued. "You, dear young people, are not the future but the now of God."

At the end of the Mass, which officially closed World Youth Day 2019 in Panama, Cardinal Kevin Farrell, prefect of the Dicastery for Laity, Family, and Life, announced that the next international youth gathering will be in Lisbon, Portugal in 2022.

"At the conclusion of this celebration," Pope Francis said, "I thank God for having given us the opportunity to share these days together and to experience once more this World Youth Day," adding that the "faith and joy" of the young people present "made Panama, America and the entire world shake!"

"I ask you not to let the fervor of these days grow cold. Go back to your parishes and communities, to your families and your friends, and share this experience, so that others can resonate with the strength and enthusiasm that is yours."

In his homily at Mass in Campo San Juan Pablo II, the pope reflected on the day's Gospel passage, which speaks of the beginning of Jesus' public ministry, when he returned to Nazareth where he had grown up and preached in the synagogue.

Not everyone in the synagogue was ready to listen to Jesus, Francis said, and the same can happen to Catholics today, when people do not believe that God can be "that close and real."

He said, "You too, dear young people, can experience this whenever you think that your mission, your vocation, even your life itself, is a promise far off in the future, having nothing to do with the present."

"We do not always believe that the Lord can invite us to work and soil our hands with him in his Kingdom in that simple and blunt a way," he continued. So instead, people prefer "a distant God: nice, good, generous, but far-off, a God who does not inconvenience us."

But that is not who God is, he said, "He is concrete, close, real love. Indeed, this 'concrete manifestation of love is one of the essential elements in the life of Christians," he said, quoting a 2006 homily of Benedict XVI.

Jesus "invites you and calls you in your communities and cities to go out and find your grandparents, your elders; to stand up and with them to speak out and realize the dream that the Lord has dreamed for you," he said.  

"Do you want to live out your love in a practical way? May your 'yes' continue to be the gateway for the Holy Spirit to give us a new Pentecost for the Church and for the world," he concluded.
