What is the way? Luke 1:16-17

16 And he will turn many of the sons of Israel back to the Lord their God. 17 It is he who will go as a forerunner before Him in the spirit and power of Elijah, to turn the hearts of the fathers back to the children, and the disobedient to the attitude of the righteous, so as to make ready a people prepared for the Lord.”
