"And you, child, will be called the prophet of the Most High; for you will go before the Lord to prepare his ways, to give knowledge of salvation to his people in the forgiveness of their sins, through the tender mercy of our God, when the day shall dawn upon us from on high to give light to those who sit in darkness and in the shadow of death, to guide our feet into the way of peace."

"... he will be filled with the Holy Spirit, even from his mother's womb. And he will turn many of the sons of Israel to the Lord their God, and 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 make ready for the Lord a people prepared." Luke 1 15-17
