Three angels proclaim messages. The first proclaims an eternal gospel for every tribe, tongue, people and nation. That is a recurring phrase throughout Revelation.
- Message one: Fear God and bring him glory.
- Message two: Babylon the great has fallen.
- Message three: Those who accepted the mark of the beast and worshiped his image must face God's wrath. This also a call for the perseverance of the saints (Rev. 14:12).
Then two angels thrust their sickles into the earth and harvest. They harvest to place clusters in the wine press of God's wrath -- devastating judgment.
