Revelation 16:3-7 The second angel poured out his bowl into the sea, and it became like the blood of a corpse, and every living thing died that was in the sea. 4 The third angel poured out his bowl into the rivers and the springs of water, and they became blood. 5 And I heard the angel in charge of the waters say, "Just are you, O Holy One, who is and who was, for you brought these judgments. 6 For they have shed the blood of saints and prophets, and you have given them blood to drink. It is what they deserve!" 7 And I heard the altar saying, "Yes, Lord God the Almighty, true and just are your judgments!"
We have in this passage of scripture the validation of Galatians 6:7-8, “Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. 8 For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life.”
Our just God is providing the fulfillment of what the unbelievers planted by persecuting the people of God and shedding their blood. The second and third bowls of wrath turned the earth’s saltwater and fresh water into the blood of a corpse. Every living thing in the sea died. Imagine the stench of all the seas. Imagine the utter chaos of all the people near the rivers and springs of fresh water.
We hear the voices of the angel and believers that are now in the throne room of God declaring that the Lord Almighty is just, holy and true. God’s judgment may not always be immediate, but it is sure. We believers are to remain confident when the unbelievers of this world hate us, persecute us and kill us. The Lord will bring justice. We are never correct when we say, “That’s not fair or just, Lord.” The Lord is just and will repay unpardoned people justly. When sin is sown, sin will be reaped. The only way for people not to reap the sin they sow is to repent of their sin and believe the gospel. If people could see the harvest reaped from sinful planting, they just might seek to plant differently. It is the job of every believer to tell people of the justice of God and of the harvest they can expect from sowing sin. It is also our job to tell people how to not reap the sin they have sown. Let us do our job and instruct people concerning the harvest they will reap unless they repent of their sins and believe the gospel.
