Most (non-radical) people I meet today, those who are family oriented, community-minded, and have a sense of social fairness and decency would readily welcome world peace. No doubt, many today pray for it. In fact, there have even been official religiously backed events collectively begging God to bring peace on earth. It seems a noble enough desire and request, why hasn't it come?
This topic is actually much deeper than most would imagine. For the sake of brevity, I will touch only on two major components.
First, God Jehovah will bring peace. Jesus himself taught us to pray to “our Father,” and ask for his “kingdom to come on earth as it is in heaven.” Jesus taught us the notion of God’s Kingdom taking over earth’s affairs nearly 2,000 years ago. He would not have done so if it were a mere rose-colored-glasses dream. It is sure to come and scripture has time-and-again confirmed and reassured that hope. Since that is God’s way of bringing peace, what about repairing and reforming the world’s governments today?
Jesus also spoke about this world’s governments but not in positive light. First he spoke of an over-arching ruler that controls all this world’s man-made systems. Who is that person? It is the same one that offered Jesus all the kingdoms of the world—none other than Satan himself. In time, just as the prophecy in Daniel foretold, God’s kingdom will destroy (not reform) earthly governments and replace it with the rulership Jesus Christ told us to pray for—God’s Kingdom. (This belief is not license for disobedience to civil authorities. The Bible indicates God allows these for our protection and a semblance of social order. However, their authority is relative to God’s authority.)
