1. The world will be filled with his fruit (1-6)
The Leviathan represents the enemy of God and his people--the devil. The vineyard of chapter 5 is unfruitful, so God removed from it his protecting hand. Here, he plants a new vineyard. He promises to water it and protect it day and night. Jesus inherited this promise, for his people are God's vineyard. He has filled the world with the fruit of his gospel.
2. The Lord who strikes his people (7-13)
God punished his people, for they did not show any understanding of the mind of their Maker. He punished them by bringing war and exile to them, so that they might repent. He will gather them one by one from the places where they are languishing as captives. He will bring them to his holy mountain to worship him.
Application: Lord, thank you for using your sovereign power to save, protect and discipline your people, as well as for destroying your enemies. Let me be planted and firmly rooted in your fruitful vineyard.
One Word: His fruit will fill the world
