The wind from heaven is the Spirit of Elijah blowing to turn the hearts of the fathers and the children toward each other. The angel spoke to Zechariah about John the Baptist, who prepared the way for the coming of the Lord. We ought to move in the same spirit and power as Elijah and John to turn the hearts-to make ready a people prepared for the Lord. Luke 1:17. John was the fulfillment of the prophecy from Malachi 4:5-6 “See, I will send you the prophet Elijah before that great and dreadful day of the LORD comes. 6 He will turn the hearts of the fathers to their children, and the hearts of the children to their fathers; or else I will come and strike the land with a curse." We are also to prepare the way of the Lord, for the second coming of Jesus.
The glory coming from the reunion of the hearts is Habakkuk 2:14 For the earth shall be filled with the knowledge of the glory of the LORD, as the waters cover the sea..
