Sorry David, but the seals have not been opened yet. The rider on the white horse is the antichrist going out conquering and to conquer.
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.
We have not had a war that has taken the whole earth
4 And there went out another horse that was red: and power was given to him that sat thereon to take peace from the earth, and that they should kill one another: and there was given unto him a great sword.
Not even WW 2 was fought on all continents. the 2 Americas and Antarctica did not have war on them.
We have not had global famine or global hyper inflation yet:
5 And when he had opened the third seal, I heard the third beast say, Come and see. And I beheld, and lo a black horse; and he that sat on him had a pair of balances in his hand.
6 And I heard a voice in the midst of the four beasts say, A measure of wheat for a penny, and three measures of barley for a penny; and see thou hurt not the oil and the wine.
Nor have we seen war and encompassing famine kill 1/4th of the population:
8 And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
Also since Pentecost, whenever a believer is martyred, they go straight o heaven and are like those who die fo natural causes. These are post rapture saints.
Sorry, but though we have seen all these phenomena happen on the earth in smaller measures, the seals are still future.
Lookup the black plague, and the great famine of 1315....
