What does God say about those who consult astrologers and rely on astrology for guidance in their lives? It's in the Bible - Isaiah 47.13-15 (NIV): "You have wearied in the multitude of view: they stand up, and save you, those who know the sky, observing the stars, announce that, after the new moons, which should happen to you! Behold, they shall be as stubble, fire consumes them, they will not save their lives from the flames: it will not be a coal to warm at, nor fire to sit before it. This will be the fate of those you get tired to see. And those with whom you have tampered with from your youth will scatter their separate ways: there is nobody who comes to your rescue. "
The Astrology is an art of divination which teaches that the provision in the sky, sun, moon and planets has an influence on people and the course of human affairs. The Hebrew word used for "astrology" literally means "divine the heavens."
Divination is the process to predict future events or revealing secret knowledge, using signs and omens or other supernatural means. God forbids the practice of divination. It's in the Bible - Leviticus 19:26 (CFB): "Do not practice the magic or divination. "
While the Israelites were preparing to enter the promised land of Canaan, God warned them not to engage in these activities. It's in the Bible - Deuteronomy 18.9, 12 and 14 (NIV): "When you come into the land which the YAHWEH thy God giveth thee, thou shalt not learn to imitate the abominations of those nations . (...) Anyone who does these things is detestable to the YAHWEH, and because of these abominations the YAHWEH thy God doth drive them out from before thee. (...) For those nations you will dispossess listened to soothsayers and diviners, but you, the YAHWEH thy God, do not allow it. "
Divination is indeed considered a grave sin. It's in the Bible - 1 Samuel 15:23 (NIV) "For rebellion is as the sin of witchcraft, and stubbornness is not less than idolatry (...). "
When King Nebuchadnezzar had a dream, he summoned the Magi (or "Chaldeans"), sorcerers and astrologers to tell him what had been his dream. How they reacted? It's in the Bible - Daniel 2.10 (NIV): "The Chaldeans answered the king:" There is nobody on earth who can say what the King asked, so no king, however great and powerful that it has summer, has asked such a thing of any magician, astrologer, or Chaldean. "
The astrologers of Babylon were unable to help the king to understand his mysterious dream. But God had blessed His pious prophet, Daniel, the true gifts of the Holy Spirit and was brought before the king to give him the key to his dream. It's in the Bible - Daniel 2.27-28 (NIV): "Daniel answered before the king and said:" What the king asks is a secret that the sages, astrologers, magicians and diviners, are not able to discover the king. But there is a God in heaven who reveals secrets, and has made known to King Nebuchadnezzar what will happen in the course of time. Here is your dream and vision that you had on your bed " . "
