How do we know God's judgment on false religion is final?

In Revelation 18 and 19, the great whore symbolizes false religion and its corruptive influence. God's judgment is declared as true and righteous, and the people of heaven rejoice over this judgment (Revelation 19:1-2). The assertion that this judgment is complete signifies that God's purposes stand against blasphemy and all forms of works religion. The victory proclaimed by the Lamb shows that He is supreme over all and will ensure that His judgment is executed, making the judgment against false religion irrevocable.
