I saw in heaven another great and marvelous sign: seven angels with the seven last plagues—last, because with them God’s wrath is completed. (Revelation 15:1)
It does not surprise me at all that God’s final, painful judgment on unrepentant mankind is described as being “great and marvelous.” God’s judgment of evil is a good a thing. Cynics will argue that God’s violent methods of judgment put him on the same level with those He is judging. They argue that all violence is wrong and therefore the God of the Bible, if He were to exist, is just as bad as the people He is punishing.
The problem with their reasoning is that it completely eliminates any possibility of justice for wrongdoers. The person who murders and rapes, they claim, should be able to live in the same state of tranquility and happiness that has been denied to their innocent victims. But this is not right. It is a good thing for the rapist and the murderer to be horribly punished in hell for eternity–unless they truly repent. God alone is wise enough and powerful enough to know if someone has repented of their sins, and Jesus alone is capable of being a sacrifice for their sins. The skeptics who claim that it is wrong for God to judge sin have a motive for their denial of His authority: their own guilt. If they were as sinless as angels, looking on from the outside, perhaps they would have a different view.
It is not good for people to be allowed to perpetually sin and harm others without consequences. God offers mercy first, but then He punishes sin. God’s punishment of sin is a wonderful, great, and marvelous thing.
