It is the tribulation,the resurrection,and the wrath of God,in that order.
God is giving the world 7 years to have their way,and cause all people who do not love Him to follow the beast kingdom,and when they take the mark,then they have given up their ability to repent,and they will make war against the saints,and God will take His children,then punish the world,and put an end to this sin business,which He has to eventually do that.
The ten horn kingdom will rule for the first three and one half years,and the world can still repent of their sins,which the 6 trumpets,6 disasters,happen,and warnings to the world to turn to God,but after the 6th trumpet the world will not turn to God,so He allows the beast to rule over them,and will crack down on the wicked,for they did not heed the warnings,and the ten horn kingdom failed at providing peace for the world,as the worse war in history happened,the 6th trumpet,that caused one third of the population of the world to perish,because nuclear weapons were used,and they did not turn to God,but turned to the man of sin,so God causes the world to follow the beast kingdom to end this sin business.
Rev 13:4 And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?
Rev 13:5 And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.
The beast has power to rule,and deceive all who do not love God for the last three and one half years,and cannot rule unless God allows it.
Rev 13:7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
Dan 7:21 I beheld, and the same horn made war with the saints, and prevailed against them.
Dan 7:25 And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time.
Dan 8:24 And his power shall be mighty, but not by his own power: and he shall destroy wonderfully, and shall prosper, and practise, and shall destroy the mighty and the holy people.
Dan 12:7 And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished.
Mat 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
Mat 24:30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
Mat 24:31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
The beast rules for three and one half years,and is the time of the great tribulation,and the saints are given into his hands for three and one half years,and when he scatters their power,then the saints will be resurrected,then the wrath of God poured on the world.
The wrath of God is not in the tribulation,why,because God is allowing the beast to rule for three and one half years,and to deceive all who do not love Him,and to make war against the saints,and if the wrath of God was in the tribulation,then how does the beast have power to rule for three and one half years,which this power to rule can only come from God.If God is giving the beast power to rule for the three and one half years,the tribulation,He is not going to against them until the time is over.
The wrath of God is not in the tribulation,why,because who do you think the tribulation is for,it is not for the world,but it is for the saints,which will be persecution on a scale that has never been done before,for it involves the whole world.
