Luke 1:13-18

But the angel reassured him, saying, “Don’t be afraid, Zechariah! God is showing grace to you. For I have come to tell you that your prayer for a child has been answered. Your wife, Elizabeth, will bear you a son and you are to name him John. His birth will bring you much joy and gladness. Many will rejoice because of him, and he will be one of the great ones in the sight of God. He will drink no wine or strong drink, but he will be filled with the Holy Spirit even while still in his mother’s womb. And he will persuade many in Israel to convert and turn back to the Lord their God. He will go before the Lord as a forerunner, with the same power and anointing as Elijah the prophet. He will be instrumental in turning the hearts of the fathers in tenderness back to their children and the hearts of the disobedient back to the wisdom of their righteous fathers. And he will prepare a united people who are ready for the Lord’s appearing.” Zechariah asked the angel, “How do you expect me to believe this? I’m an old man and my wife is too old to give me a child. What sign can you give me to prove this will happen?”
