Now how can the average Christian break all of this symbolism down, so they can really understand what it is saying. Most ministers can't break it down. If the author would have presented it in plain language it would have only taken two sentences to explain it. By the way the horses are referring to the different races. It is showing how the different races are being used to build the kingdom of the antichrist. As you notice there is someone riding each horse.
Some say that the four horsemen represent the four corners of the earth: N, S, E, W.
Some say that they refer to constellations.
