Luke introduces the ministry of John the Baptist by saying that ‘the Word of God came to John in the wilderness.’ John’s message is one of repentance; a radical change of heart and mind. Like the Old Testament prophets who went before him, John challenges the people to turn back towards God with their whole hearts. The promise is that repentance will bring forgiveness; God in his mercy will set his people free from their sins. John’s prophetic word is addressed to us, too. In Advent, we are challenged to repent and turn back to God. By our repentance, we prepare the path for the Lord, clearing away the obstacles that stand in his way, so that we will be ready to welcome the Son of God when he comes.
