The riders of the Four Horses (the Four Horsemen) are beasts that are released upon the earth. A white horse brings war, setting out to conquer lands and nations. Islam’s Mahdi is the white horse who we call the Anti-Christ. There seems to be a general belief that the Ant-Christ is a peacemaker; however I fail to see it. In Dan. 8:23 he is seen as, “a king of fierce countenance.” War, in general, is represented by the red horse. As for the black horse, it depicts depression and famine. God distinctively instructed that horseman not to hurt the oil and wine, which are more expensive things. This is an indication of a worldwide depression as well as famine. The green horse, also known as the pale horse, is death. “Wild beasts of the earth” might mean viruses, a hint that the pale horse brings plagues (Revelation 6:1-8).
Look ahead at the topics of nuclear weapons (nukes).
And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind (Revelation 6:12)
Now this is allegorical, meaning figurative. However, it leaves no question of its reference to falling stars. Re-entry vehicles coming in from ICBMs look like stars falling from heaven. This is confirmed because it says:
And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places. And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains (Revelation 6:14-15).
That is a whole lot of nukes. Why would they hide in the mountains, if it were not because of nuclear war? No other logical explanation exists.
And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb: for the great day of his wrath is come; and who shall be able to stand? (Revelation 6:16-17).
An interesting thing here is that prior to the seven horses beginning their gallop, the earth has seven billion people, which is today’s population. Earth’s populace decreases after the horses initiate their gallop. When the pale horse rides, a fourth part of the earth of the Earth are killed, taking the total number of inhabitants down to 5.25 billion and that is prior to the destruction by nukes. The Bible does not say how many the nukes kill. Without even taking the nukes into consideration, there are only one billion people left on the earth by the eleventh chapter of the Book of Revelation.
