Re: biblically speaking!
Yes, the four horses can represent the four corners of the world, but why the different colors. You could just use the same color horse to represent the four corners of the world. This Biblical revelation gives each horse a color similar to the races of people in the world. It's refreshing to get insight from you. God gives us revelation to makes us think. Most Christians think that God gives us brains then gives us something to insult the brain he gave us with the trinity belief. If you keep using insight then you will come to a rational understanding of that belief and why it was given to Christians.
