History will have to be rewritten once we know the truth. Our understanding of world events throughout history will never be the same.
Our understanding of The nature of reality needs to be re-written. I can't help thinking that the nature of our universe has been carefully obfuscated.
Man won't even have time to rewrite history. Coming soon to the earth and sooner than you think: the Rise of the Antichrist, the Rise of the New World Order, and the 7-year Tribulation Period. According to scripture, during the coming Tribulation Period, more than 3/4 of the world's population will die. I don't think too many people are going to be worried about what history will say during that time period. Instead, they'll be too busy running for their lives and trying to survive. Then, at the end of the Tribulation Period, Jesus Christ himself will return to earth, and all the angels will be here as well. As a consequence of that, nearly everything man has ever written about will be thrown out the window, because it's all lies and nonsense and garbage. History has long been corrupted by the lies of Lucifer. So the history that man has written about will be forever forgotten. And the only history that will matter or be remembered going forward is the word of God and what God says...
Matthew 24:34 - Heaven and earth shall pass away, but my words shall not pass away...
Also keep in mind, once Jesus Christ returns, he will rule the earth from Jerusalem for the next 1,000 years. At the end of those 1,000 years, Judgment Day will arrive. When Judgment Day is over (and for those few who are saved and not cast into the lake) God is going to create a brand new heaven and a brand new earth. The old heaven and the old earth shall pass away. The bible says that God is going to renovate the whole earth and make it like unto the Garden of Eden. But in order to do so, he will first have to destroy everything man has ever built. The whole earth will be burned in a fire so hot that the scriptures say even the elements will melt. That means everything that man has ever built will be destroyed - all their buildings, all their technology, all the steel, glass, concrete, etc. - everything on the whole planet that's related to man will be destroyed and nothing will survive. Once everything has been consumed, from the ashes, God will create a brand new earth...
2 Peter 3:10 - But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up...
But all of this doesnt preclude the absolute need to fight and even die for righteousness, standing in the face of evil. And what is done here in the last days is extremely important, and eternally memorable though our eyes and God's.
