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.
For they have shed the blood of saints and prophets, and you have given them blood to drink. It is what they deserve!"
And I heard the altar saying, "Yes, Lord God the Almighty, true and just are your judgments!"
This song of worship comes as a direct response to God’s retributive judgment on those who have rejected and rebelled against Him. It praises God for His justice. The praise follows a simple line of thinking. God is just because He brought the judgments. He acts in judgment and that alone is cause for Him being seen as just. Secondly. God acts in such a way that those who are judged are judged in a deserving manner. There is an irony in the judgment that turns the water to blood, since the beast and his followers have led a bloody persecution against God’s people. The punishment fits the crime, and that is just.
Thirdly, God is just because He is the Almighty. God has all power at His disposal to dispense His justice. He is remarkably restrained when one considers that fact! He could just obliterate the world of humanity at any time, but does not do so. And the final observation about His justice is that He is true. He does not cause further sinful behavior, neither are His judgments subject to debate about their moral equity. He is true and so are His actions.
I do not pause to consider these truths enough, because like most Christians, I tend to associate judgment with rage or anger. But Your justice is fundamental to Your very person and nature, as the angels sing of in this passage. May I be equally impressed and worship You Who are just and true.
