The Bible prophesies this date by interpreting the seven headed ten horned beast as: The seven heads are the first seven emperors.
Why? Did Jesus having 7 horns and 7 eyes mean he was one of 7 emperors? No. Of course not. But there
was a reference to the 7fold spirit! What's that about? The Holy Spirit isn't the 3rd person in the Godhead any more? No. The number is being used in its
Jewish sense of God's perfection.
Try to be consistent with Jewish number symbolism please! When Revelation uses 7 of Jesus eyes and horns, it is referring to God's perfect authority and knowledge.
Chapter 12-14 recounts the gospel story so far, with Mary giving birth to Jesus and Satan opposing the baby from birth. Satan (the dragon) has 7 heads and 10 horns. He is imitating Jesus perfect power and authority.
The 7 horned 10 headed
beast is trying to imitate Jesus; but in the end it mimics Satan. The number patterns are repeated for a reason. The terrifying beast is Rome which persecuted God's people and, from an Ancient Middle Eastern world-view and cosmology, basically controlled the
whole world. It might sound silly to modern ears, but to them Rome really did rule the world.
And in describing Rome, and how Christians were to act towards their persecution, he describes how Christians should act in all situations of 'beastly' government sponsored persecution.
Remember, ONLY this reading is consistent with the way John describes the purpose of the whole book in the first verse!
1 The revelation from Jesus Christ, which God gave him to show his servants what must soon take place. He made it known by sending his angel to his servant John, 2 who testifies to everything he saw—that is, the word of God and the testimony of Jesus Christ. 3 Blessed is the one who reads aloud the words of this prophecy, and blessed are those who hear it and take to heart what is written in it, because the time is near.
The time really was near, as the Roman persecution was just about to burst forth. And, even though we in the western world are not under persecution now (praise the Lord!), the time remains near. Because while we might not be
persecuted, we can face
prejudice, and we must resist the temptation to trust in worldly security and authorities rather than God. So while it is primarily
about Rome, just as the books of Corinthians were about and to the church in Corinth, the wisdom in the book can be applied to today. Well, to every age of Christians actually, including the last 2000 years.
Otherwise, reading it as you do, the book is
mostly irrelevant
most of the time.
