The Bible says the Roman Empire shall not lose their dominion until God puts them down,which at the end time they will split the world in to ten section with a leader in each section,which John said is a kingdom to come in the future,and will continue a short space,three and one half years,which the little horn comes from the ten horns.
The prince to come shall come from the people that overthrew Jerusalem,the Roman Empire.
Daniel chapter 9:26 speaks of the antichrist,and continues speaking about him in verse 27,that he will establish a 7 years covenant with Israel that will be a peace plan in the Middle East allowing the Jews to rebuild their temple,and go back to animal sacrifices,which the man of sin will step in to their temple midway through the 7 years,and tell them to stop animal sacrifices,and that he is their God and Messiah.
Judas is not the antichrist for he is not of the Roman Empire,which when it mentions him as the son of perdition it is because he was influenced by Satan and betrayed Jesus,which the last king will be mighty but not by his own power,but gets his power from Satan,and goes against Christianity,so he is known as the antichrist,and son of perdition.
The great tribulation is for three and one half years,but the man of sin will establish a 7 years covenant giving peace in the Middle East,and then will work for the first three and one half years pushing the new age movement,which is about harnessing the power of nature,which he convinces the world he harnessed the power of nature and achieved power midway through the 7 years period.
The 7 years period is a future event.
During the first three and one half years the world will operate by the ten horn kingdom that covers the earth,that only rules for a short space,three and one half years,but they failed at maintaining peace as the world experienced the worse war ever,and they do not trust government anymore to maintain peace on earth,and governments collapse,and they turn to the antichrist.
During the first half of the 7 years period there is a unified religious system which all religions are valid for spiritual evolution with a false interpretation of Christianity,Islam,and Judaism,but when the beast claims to be God by harnessing the power of nature,and there is no personal God to help mankind,so the beast is top dog,then the unified religious system collapses.
That is the plan of the beast to cause the collapse of all governments and religions,and to make war one at a time with Islam,Christianity,and Judaism,because of their belief in a personal God.Islam during the first three and one half years which that war is why the world turns to the beast to maintain peace,and in the middle of the 7 years period,war against the Christians,and then after the tribulation is over,then war against the Jews,the battle of Armageddon.
There are 7 kings,5 are fallen.1.Egypt 2.Assyria 3.Babylon 4.Medo-Persia 5.Greece.One is at the time wrote Revelation.6.The Roman Empire 7.Ten horn kingdom which will rule for a short space,the first three and one half years 8.The last king,the beast,will rule for the last three and one half years,which is of the 7 beasts,which means Satan influenced all those kingdoms.
It is a 7 years period and not a three and one half years period,for the first three and one half years did not occur in the past.
The 7th king,the ten horn kingdom,fails at maintaining peace,and they turn to the beast,which the one of his heads were wounded,but the deadly wound was healed,which means the 7th king,the ten horns that failed caused the world to lose hope for having peace on earth,but the beast restored order and gave them hope,and the deadly would was healed,and convinced the world he harnessed the power of nature and obtained power,and the world says who can make war against the beast,for they believe he has the power to establish his kingdom and no foe can stand against him.
The 7th king,the ten horns,hand their power over to the beast,so they have to be there when the beast comes to power,also the wound of the ten horns is healed so they have to be there when the beast comes to power.
7 years period,the ten horns rule for a short space,the first three and one half years,they failed,they hand their power over to the beast,and he comes to power and takes over the world,for the ten horns cover the world,and he rules for the last three one half years.
