Very good post, and yes- Revelation is mostly symbolic. It was a vision John had, and could not accurately describe what he was seeing. For example, in John 9:3 he mentions locusts and scorpions. Could John be talking about an assault helicopter?
No, he could not. He probably meant " locusts and scorpions"
After all, John would not know what an assault helicopter was, so he just described things he was familiar with in the way he knew how.
So, you're suggesting that God sent John a vision that God knew John would not understand? What would be the point of this?. Why didn't John then draw a helicopter? Galileo drew helicopters.
Why does the Book of Revelations have to have a meaning? Isn't it far more likely that it is the ramblings of a mad man? Why are we trying to understand a schizophrenic? Are there any other schizophrenics that you believe are "revealing" things?
Why must the Book of Revelations apply to the early part of the 21st century? Don't you realise that each period throughout history could serve for what John ranted on about?
Do you remember when your deity said, "1Th:5:2: For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
2Pe:3:10: But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up."
Your deity didn't say that he would be giving clues. He didn't say, "Well, not actually like a thief in the night, because I will be sending some nutter to give you an incomprehensible message that, nevertheless will contain a few hints!"
Look, holy buckets, the world has been filled with Chicken Littles worried about the sky falling on their head. You would have thought that, by now, we would have become used to failed prophecies.
But more to the point, you are expecting me to believe that 7-headed dragons will suddenly appear, magicked out of nothing, fully formed and out of nowhere? Now, how likely is that?
Here is Graybeard's prophecy, "Don't worry, the world is not going to end."
