Commentaries:
Jesus says that Satan “was a murderer from the beginning” and “is a liar and the father of it” (John 8:44). Is this passage in Revelation 21 wrong because the unrepentant, unbelieving, lying, and murderous demons will still be alive? There is no contradiction. They will have been burned up in the Lake of Fire.
