One of the striking things in reading the first 26 or so chapters of Ezekiel is the judgements that Ezekiel is given by God to pronounce on God's people but also on the nations which surround Israel. And God's purpose in judging is that both his people and these other nations would know that "I am the LORD".
God wants his people to understand that their judgement is the result of their sin and so that they may know he is God and turn back to him. But he also does not want the nations around about to assume that he is not God or no better than their gods because Israel is taken into exile, but to realise that he is the only true God over not just his people but the whole world.
Our God is God over all.
