God is going to give the world 7 years to have their way,and cause all people that do not love Him to follow the beast kingdom.
The first three and one half years the world will operate by the ten horn kingdom,the world split in to ten sections with a leader in each section,having a one world religious system where all religions are valid for a spiritual benefit,and fundamental Christianity,Islam,and Judaism,will be interpreted by the main interpretation of the unified religious system,causing people to not embrace the truth of the Bible,and not listen for all are valid,and Christianity will rapidly decline in reaching the world.
This is the falling away first.
Then the man of sin will address the world that he is God,by harnessing the power of nature,and achieving power higher than any other person of the occult,nature worship,can achieve,so he is top dog.
The saints will not be gathered unto Christ until those two things occur.
God is given the world 7 years to have their way,and cause all people that do not love Him to take the mark of the beast,so God can end this sin business,for when they take the mar,salvation is no longer available,and when they make war against the saints,and scatter their power,then the saints shall be gathered unto Christ.
The Bible says when the world says,Peace and safety,then sudden destruction comes upon them,and they shall not escape,which is when the world comes together to try to achieve peace on earth,and slowly cut God out of the picture,which the beast kingdom does not regard any god.
The Bible says that the saints will not be deceived by that,for they will know it is not the operation of God.
The Church of Philadelphia,Jesus did not have anything against them,and because of that He would keep them from the hour of temptation,that shall come upon the whole world,to try all them that dwell on earth,which there is only one temptation that can come upon the whole world,and that is when they say,Peace and safety,for those that are not in the truth of Christianity will be tempted by it,for they do not have the Spirit,but are hypocrites.
The 6 trumpets are 6 disasters that happen on earth,that the world knows about,but after each one they keep trying to solve their problems instead of turning to God.
After the 6th trumpet which causes one third of then world to die,and describes nuclear weapons as the cause of so much destruction,God said they still will not repent of their sins,and they will not turn to God,so God gives them the man of sin to rule over them(Revelation 9:12-21).
War breaks out in heaven between Michael and the angels,and the Dragon and his angels,and the devils are defeated,and cast to earth,which Satan appears as the beast,the man of sin,to deceive all who do not love God,and to make war against all who hold the testimony of Jesus(Revelation 12).
The Bible says the earth has become the habitation of devils,and the hold of every foul spirit,and the cage of every unclean and hateful bird,which the earth becomes the devils holding cell,and Satan is no longer the prince of the power of the air.
The strong delusion that God will send all those who do not love Him,and have pleasure in unrighteousness,and not in the truth,is that they will be deceived by a devil,and will follow the beast kingdom,which is a delusion that cannot snap out of like someone can snap out of delusion now.
When the devils are cast to earth,which happens because the world keeps trying to achieve peace on earth,and solve its problems,and will not turn to God,the devils will deceive all people that are not in the truth,because they have pleasure in doing wrong,and not right,and they will follow the beast kingdom,and take the mark,and then make war against the saints,and scatter their power,then comes the end when the Son shall deliver up the kingdom to the Father,and the saints will be gathered unto Christ.
