[In Advent] "we hear in the Gospel the beginning of the ministry of Saint JEAN BAPTIST. He appears in the desert and calls people to conversion so that they may prepare for the coming of the Lord. His call reminds us that Advent is not only a time of waiting, but also of interior preparation. "Prepare the way of the Lord, make straight his paths" (Luke 3:4). John's message challenges us to examine our lives. What "rough paths" and "crooked roads" are there in our hearts? Where have we perhaps distanced ourselves from God or lost sight of our fellow human beings? John invites us to remove these obstacles and reorient our lives. But his call has not only a personal dimension, but also a social one: the way of the Lord is a way of justice, peace and reconciliation. When we pave the way of the Lord, we bring light into the darkness of the world and hope into the hearts of people." (Text: Michael Inden, Diocesan President of the KAB in the Archdiocese of Cologne)
