Our chapters today in Zechariah 13 & 14 and Revelation 15 & 16 may be the most dramatic in the whole Bible with their descriptions of events leading up to the final judgments of God on the forces of the nations that are blind to the reality of his existence.
Some of the ‘jigsaw pieces’ of events we are able to put into place, others tentatively so, but with several we are unable to fit them into place at this stage of human history. The wonderful thing is that God’s final judgments lead to the declaration “there shall never again be a decree of utter destruction.” [Zech 14 v.11]
In Revelation we are given a similar picture, an ultimate era after God’s final judgments, a time when God, through Christ, will ordain a time of peace for a 1,000 years.
We are told “the wrath of God is finished” [15 v.1] “and they sing …  ‘Great and amazing are your deeds, O Lord God the Almighty! Just and true are your ways, O King of the nations!  Who will not fear, O Lord, and glorify your name?  For you alone are holy.  All nations will come and worship you, for your righteous acts have been revealed.’ ”  [v.3,4]  Christ will reign for God as “the King of the nations.”
But God’s righteous acts first of all accomplish a cleansing of the earth of evil, expressed in the symbols of a dragon, a beast and a false prophet [16 v.13] to describe the secular and religious powers that are brought to nothing. Involved in this is the “battle of the great day of God Almighty” – that is – “Armageddon” [v.14,16] which is climaxed by “a great earthquake such as there had never been since man was on the earth … and the cities of the nations fell.” [v.18,19]
Awesome!  Intensely frightening!  In the midst of these verses is a personal message for true believers, “Behold. I am coming like a thief!  Blessed is the one who stays awake, keeping his garments on …”  [v.15]   these are the “garments of salvation” – read Isaiah 61 v.10. Our prayerful reading and meditation and worship of God here and now will create for us these essential “garments.”
