I have no problem with the notion that the Bible contains a fair amount of astrological information. What is forbidden, is what Herod did or tried to do. He tried to use a God-given sign to thwart the will of God. Seeing a sign and understanding what it’s prophetic meaning is, is not divination or fortunetelling. Otherwise, recognizing the impending fulfillment of any sort of prophecy would be divination or fortunetelling.
There is a difference when John says “he saw a sign of a woman” and then men try to fit astronomical data to fit what he saw....as opposed to Jesus when he says “all nations will mourn when they see the sign of the coming of the son of man in the heavens”. Jesus is predicting that a sign will occur that everyone will be able to see and they will know it is he that is coming onto the scene. The Bible predicts the loss of 8 hours of our 24 hour day with the loss of our moon light...that is a sign that the Bible says will happen. John saw the sign of a woman, he did not say we would see it though he did predict other signs that men will see and hear. Do you understand the difference?
