When Zechariah saw him, he was startled and was gripped with fear.  But the angel said to him: “Do not be afraid, Zechariah; your prayer has been heard.  Your wife Elizabeth will bear a son, and you are to give him the name John…. And he will go on before the Lord, in the spirit and power of Elijah, to turn the hearts of the fathers to their children and the disobedient to the wisdom of the righteous – to make ready a people prepared for the Lord.”  Luke 1:12-13, 17
