Caesar's messengers didn't go round the world saying, 'Caesar is lord, so if you feel you need to have a Roman-empire kind of experience, you might want to submit to him'.

If what we want is God’s justice, coming to sort things out, we will do better to get entirely out of the way and let God do his own work, rather than supposing our burst of anger (which will most likely have all sorts of nasty bits to it, such as wounded pride, malice and envy) will somehow help God do what needs to be done.
