In the first reading the prophet Isaiah speaks of God leading his people to their homeland: “Like a shepherd he tends his flock: he gathers the lambs in his arms, he carries them in his bosom, gently leading those that are with young.” At the appointed time John the Baptist prepared the people by repentance for sins and baptism in water for the coming of the Messiah.
During Advent we prepare for the joyful celebration of the birth of God-made-Man. We also prepare for his glorious Second Coming at the end of time.
How do we prepare for his Second Coming? We do our best to live in accordance to his commandments; we do our share in proclaiming the Good News of the Kingdom of God; we do our share in seeking the stray in their way to the heavenly kingdom.
