The imagery - Revelation is allegorical - or do you expect that John actually saw Jesus wih a two-bladed sword out of His mouth? Or was that the significance of the power of His words?
Which is ignorance or cultic sophistry. JWs likewise deny eternal punishment in Hell since the word geenna refers top a garbage pit. If taking things literally mean that there can be no symbolism involved then you can also join those who deny Is. 53 speaks of Christ, (the "Lamb of God") since it also uses allegorical language.
However, If taking things literally mean that there can be no symbolism involved then it requires the sort of exegetical gymnastics that you must engage in to relegate most every end-times prophecies of the New Testament as being fulfilled in AD 70A.D.
If you want to contend this, please provide a list of all prophecies of the New Testament that you do not consider to have been fulfilled.
If you are unwilling do to this, then we should focus on what is most important, that of experiencing Biblical regeneration thru personal heart-purifying faith in the risen Lord Jesus to save the sinner on Christ's account and credit, by His sinless shed blood, and thus follow Him.
