A hundred years ago, Christians reading the Book of Daniel could not have possibly understood what he wrote concerning the technology in the last days (Dan. 12:4), let alone the material found in the Book of Revelation. And even today, with all the scientific advances, there are still prophetic statements in the Bible which are difficult to understand. For instance, when will the conflict occur in which two of the main players are Gog and Magog (Ezek. 38-39; Rev. 20:8)? And why are the armies of the Lord and His opponents riding on horses (Rev. 19:11-21)?
Some have suggested that the reason for horses as the mode of transportation is possibly due to the explosion of nuclear weapons detonated in or above the earth’s atmosphere. An "E-Bomb" can create an electromagnetic pulse (EMP), which acts like a stroke of lightning, but is much stronger. It could seriously damage electronic devices such as communication systems, computers, electrical appliances, and transportation ignition systems. Without the ability to use modern weaponry, the best an army could do would be to ride horses.
That all makes good sense, except for one thing, if all electronic devices are damaged or rendered useless, how is it possible that the entire world could still see live satellite pictures of bodies of the two witnesses lying in the street (Rev. 11:7-11)? And what about the mark of the beast? If electronic scanners are out of the picture, how will it be possible to read an implanted computer chip?
It is obvious to me that although our understanding of much of the "symbolic language" of the Bible has increased markedly over the past century, there are still plenty of questions to keep even the wisest scholar humble. Why will Jesus, His army from heaven, and the army of Satan ride on horses? I do not know, but they will!
"And the shapes of the locusts [were] like unto horses prepared unto battle; and on their heads [were] as it were crowns like gold, and their faces [were] as the faces of men. And they had breastplates, as it were breastplates of iron; and the sound of their wings [was] as the sound of chariots of many horses running to battle. And thus I saw the horses in the vision, and them that sat on them, having breastplates of fire, and of jacinth, and brimstone: and the heads of the horses [were] as the heads of lions; and out of their mouths issued fire and smoke and brimstone. And the armies [which were] in heaven followed him upon white horses, clothed in fine linen, white and clean. That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all [men, both] free and bond, both small and great" (Rev. 9:7, 9, 17; 19:14, 18).
