Firstly, I would say that throughout history we see famine and war and pestilence and death. Such things tend to accompany one another. It's a fairly casual observation.
Regarding the End Times, I do not doubt that there will be a sequence, and that the sequence is determined. It may be mincing words to say that the 4 Horsemen do arrive in a sequence 1-2-3-4 -- but they are all coming, are they not? Therefore I say that they ride together. They simply don't all arrive at the same time. But they will arrive.
Thank you for clarifying.
Regardless of how you came to say what you said, it has definitely affected my thoughts on the subject.
With this Ebola outbreak, widespread plague may come to earth much earlier than I have placed it on my timeline. That possibility exists if the horsemen have parallel or even just overlapping rides.
Here is my attempt to tie it all together. I am not a prophet.
