Luke 1:16-18

And he will turn many Israelites to the Lord their God. He will be a man with the spirit and power of Elijah. He will prepare the people for the coming of the Lord. He will turn the hearts of the fathers to their children, and he will cause those who are rebellious to accept the wisdom of the godly.” Zechariah said to the angel, “How can I be sure this will happen? I’m an old man now, and my wife is also well along in years.”
