But it was a book of signs as it says at the beginning (it was 'signified, given by signs'). It was not intended to be taken literally. It was intended to convey the future in signs. That is why it has had a word for all ages.
No it was a Book to be TAKEN LITERALLY, understanding the few symbolisms used. THE LETTERS TO THE CHURCHES PROVES THAT. You think it is ALL symbolism, I BELIEVE it is only about 10% symbolism, and the REST is to be understood LITERALLY.
Beast is Symbolism for the LITERAL Antichrist (Satan possessing a World Dictator)
Frogs are Symbolism for LITERAL Demons
Beast with 10 Heads is a LITERAL 10 Nation Confederacy
Horns and Mountains are LITERAL Kingdoms or Nations
Bowls and Trumpet judgements are Symbolism for the LITERAL Judgements from the JUSTIFIED WRATH OF GOD.
Locusts with Scorpion-like Tails are Symbolism for LITERAL Demons that WILL be loosed from the Abyss to TORMENT the inhabitants of earth.
Beyond that it is to be understood just plain LITERALLY as what WILL HAPPEN IN THE FUTURE.
