The judgment of the world has already occurred at the cross. There is no more wrath from God against people’s sins forever. Last Day Judgment is the judgment of the Devil and his angels’, which unbelievers will inherit apart from Jesus.
God is not judging anyone for their sins anymore, but there is a godly, New Covenant vengeance that God takes to defend and protect those who believe on Him.
