Hello MarcR,
With all due respect, the seals, trumpets and bowl judgments have not yet begun. Through these are how God's wrath is going to be poured out upon the earth and they are not going to be events such as WWI and II that have come and gone. These are going to be events that will take place during that last seven years leading up to the Lord's return to the earth to end the age which will decimate the majority of the population of the earth and dismantle all human government.
In addition, the 1st seal, the rider on the white horse, is symbolic representing the antichrist. Since the antichrist has yet to be revealed, then the 1st seal could not have yet been opened.
The wrath of God has been revealed from heaven and continues to be revealed in those who exchange the truth of God for a lie. The Antichrists those who insist we need men(seen) to teach us usurping the teaching ministry of the anointing one, the Spirit of Christ are already here, as Satan works in the heart of men to deceive them.
Peter makes a good example of the working of the antichrists (many) when he blaspheme the name by which we are called heavenward in respect to the Son of man .as that seen . Blasphemy against the Holy Spirit not seen is not forgivable. We must walk by faith, the unseen..
Its the last day not last days or what you call seven years. It is the day of the second resurrection as the final, as well as the last trump, judgment for the world. The new heaven and earth have appeared, the former things of this world will not be remembered or ever come to mind.
Christ will not reign in the flesh on this corrupted world . He is not a man as us.
If you are looking for him to put on the temporal flesh for another demonstration it simply will not happen. We do not know Christ that even though some did .never again in that way forever more .It has nothing to do with world war 2 or any world war that is involve with the political issues of nations.. We walk by faith the unseen.
It is why the book of Revelation which is given from the standpoint of the last day the Lord's day it is signified .using the things seen to give us the eternal spiritual understanding hid from the lost. Without parables, Christ the Son of God spoke not, and the book of Revelation is not exempt.
What will shorty come to pass in the verse below is the last day, (not days) signified as the Lord's day( not days) the last trump, as the one voice of God .
Rev 1:1 The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:
Rev 1:10 I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet,
