therefore thus says the Lord GOD: Behold, I, even I, am against you. And I will execute judgments in your midst in the sight of the nations.
The pronouncements against the city of Jerusalem by God are very severe. This is not enjoyable reading. Anyone who gets excited about God's display of His displeasure at sin and pouring out His wrath in judgment is not normal. It is terrifying to consider. God was going to allow Jerusalem to be ransacked and the people to suffer horribly in consequence for their sin. And the world would see it.
There was a reason for the humiliation, hunger, shame, and public display. The city had sinned in a dramatic way that was on display on the world stage. The nations around them had watched them abandon and defy God. The public humiliation they would endure was meant to be instructive to the watching world as well. It was a witness to the power of God in administering justice. It would instill awe and fear of the Lord.
By having His prophet Ezekiel declare these things in advance, God was showing His people that He was sovereign. He was present in their judgments. He was administering the curses of the covenant due to their long disobedience and disregard of Him. This was not pretty, but it was powerful.
I don't believe for one moment that God's person or nature has changed since this time. He can still choose to display His glory in judgment and still does. In fact, the scriptures indicate that He will do so with the entire world at the future moment known as the Day of the Lord. I am not afraid personally for that reality, but I am in awe of it and honestly am not really anticipating it with glee. It makes me aware of the awfulness of human sin and the holiness of my great God.
