The Tribulation begins with the antichrist signing a peace deal that gives Is--el total security and the right to build a third temple.

The antichrist is seen as a philanthropist, a genius and the man who saves the world from itself. He leads the world in forming a global government with ten regions. At the beginning he validates all belief systems....apart from Biblical Christianity, which is now absolutely reviled and hated.....and he is embraced by the world. He forms a ten region world government.

The judgements of God start and he deals with it the best he can. Pestilence (very well could be results of the vaccine a few years from now...mass death from sickness), war, famine, etc.

The mark of the Beast happens after the 3.5 year mark of the Tribulation. The perfect world the antichrist envisioned is falling apart totally and he goes into the J---ish temple and declares himself god on earth and desecrated the temple. He then implements the mark of the Beast and anyone not agreeing with everything he says and does is killed. To show allegiance to the AC, a person has to take a mark showing they are part of his empire. A person will know if they take it, it will be in allegiance to him, not a medical thing.

What you are seeing now is the setup. The beast system technology is ready to go. The vaccine will depopulate and there may be a vaccination component to the mark of the Beast. But we are not there yet according to the Bible.

The Tribulation is mass death, a third of people dying from famine and pestilence, mass war. Etc.

Jesus promised His church, the Body of Christ on earth, that we would not got through God's wrath. The Trib is entirely God's wrath. Place your faith in Jesus Christ and His work on the cross, He has risen and He will take His body out of the earth before the Trib begins.

Christianity is not a religion. It is a person. Jesus Christ. He did it all. Believe and be saved, follow Him.
