Luke 1:15-17

For he will be great in the sight of the Lord, and shall drink neither wine nor strong drink. He will also be filled with the Holy Spirit, even from his mother’s womb. And he will turn many of the children of Israel to the Lord their God. He will also 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 make ready a people prepared for the Lord.”
