In both Exodus 23:24 and Leviticus 20:23 the Lord was emphatic…Don’t bow down to foreign gods, and you must not follow their customs and practices…and this included their response and rituals  towards signs in the sky.  The world has always reacted to natural disasters such as earthquakes, tornadoes, and hurricanes with alarm…for there is nothing humanly possible we can do to control them.  But as Believers, we know these types of signs are finger-marks of God…indicating His spiritual purpose…signs of the End of the Age.  We only have to read the words of Jesus in Matthew 24:6-8 for clarification, ” You will hear of wars and rumors of wars, but see to it that you are not alarmed.  Such things must happen, but the end is still to come.  Nation will rise against nation, and kingdom against kingdom.  There will be famines and earthquakes in various places.  All these are the beginning of birth pains.”
