There Was War in Heaven Michael and his Angels Fought the Drakon and his angels

This age(aeon) will end with the Tribulation Period.  The Tribulation Period marks the end of the so-called Church Age.  Peter even writes that judgement will begin at the House of God.  This is remarkable because he cogently comtemplates the destiny of the ungodly who know not God.  The Tribulation Period will begin with the falling away first of the professed church.  The confessed church will be with Jesus in glory.  However, during the Tribulation we are told that the devil will be cast out of heaven and his wrath will be great because he knows that his time is short.  The devil knows that the wrath of the Lamb is coming upon this sin-cursed world.
