The first seal in Revelation 6 is open right now in real life. Out of everything that will happen in Revelation, this is the very first of 7 seals then 7 angels then 7 vials that are poured upon Earth.
KJV | Revelation 6:2 - And I saw, and behold a white horse: and he that sat on him had a bow; and a crown was given unto him: and he went forth conquering, and to conquer.
The white horse went forth conquering. Not mentioning to kill but to conquer as on a conquest. The street teachers are conquering when they give their testimony on the streets. When they successfully wake up ISRAELITES that are sleeping on the truth is the conquest (1 Esdras 4:38). There are ISRAELITES on a conquest all over Earth conquering people with their prophecy. Prophecies are preachings from the Bible and to make The Sense; this require a minimum of two witnesses. In Revelation 19 the white horse comes from Heaven (Christ Second Coming) with conquered ISRAELITES in Revelation 6:2 for the marriage (Revelation 19:7) of World War 4 (Revelation 17:14, 19:11,19).
KJV | Revelation 19:11 - And I saw Heaven opened, and behold a white horse; and He that sat upon him was called Faithful and True, and in righteousness He doth judge and make war.
After the street teachers there is Civil War 2 in America and civil unrest in other lands as the third seal (Revelation 6:5-6). That will evolve into World War 3 as the fourth seal (Revelation 6:8). This is three of the seven seals on back of a book that was in GOD's right hand in Revelation 5:1.
