This verse seems so relevant to the current events in our world. I know we are not in the great tribulation, maybe it's a shadow of things to come.
3 When he opened the second seal, I heard the second living creature say, “Come!” 4 And out came another horse, bright red. Its rider was permitted to take peace from the earth, so that people should slay one another, and he was given a great sword.
Maybe it's a wake up call!
