In Luke, we read a part of the Advent message that is often forgotten. In Mark it was predicted that someone would come to announce the Saviour. In Luke we read about Zechariah and Elizabeth both being true to God and childless although having prayed for years for a child. Zechariah was serving as incense burner within the temple when an angel told him Elizabeth would bear a son to be called John. When he did not believe right away the angel made sure he could not talk until the baby was born. When the baby was born he wrote the name John and then he could speak.
Birth is a miracle and when a couple is old it is even more of a miracle.
It is interesting, we ignore this miracle so often â€“ focusing on Mary visiting Elizabeth when John jumped in Elizabethâ€™s womb and forget how God worked that all out.
