Before we can speak of God and with God, we need to listen, and the liturgy of the Church is the "school" of this listening to the Lord who speaks to us.
Finally, he tells us that every moment can be propitious for our conversion.
Every day can become the today of our salvation, because salvation is a story that continues for the Church and for every disciple of Christ.
This is the Christian meaning of "carpe diem": seize the day in which God is calling you to give you salvation!
Pope Benedict XVI
