To prepare a people prepared for the Lord

But the angel said to him, “Don’t be afraid, Zacharias, because your request has been heard. Your wife, Elizabeth, will bear you a son, and you shall call his name John. You will have joy and gladness, and many will rejoice at his birth. For he will be great in the sight of the Lord, and he will drink no wine nor strong drink. He will be filled with the Holy Spirit, even from his mother’s womb. He will turn many of the children of Israel to the Lord their God. He will go before him in the spirit and power of Elijah, ‘to turn the hearts of the fathers to the children,' and the disobedient to the wisdom of the just; to prepare a people prepared for the Lord.”

Luke 1:13-17 WEB
