The wrath of God does not occur until after the 7 years period,for God is allowing the world to have their way so He will not intercede until the 7 years period is over.
Repentance,and salvation,is still available to the world during the first three and one half years,so the wrath of God would not be there for they do not deserve the wrath of God while salvation is still available to them.
The beast has power to rule for the last three and one half years,so the wrath of God is not there,for if it was how does the beast have power to rule for the last three and one half years,and this power can only be given him by God.
God is allowing the world 7 years to have their way,and do what they want to do,and cause them to rebel against Him,so His wrath is not upon them until after the 7 years period is over.
Rev 9:18 By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths.
Rev 9:19 For their power is in their mouth, and in their tails: for their tails were like unto serpents, and had heads, and with them they do hurt.
Rev 9:20 And the rest of the men which were not killed by these plagues yet repented not of the works of their hands, that they should not worship devils, and idols of gold, and silver, and brass, and stone, and of wood: which neither can see, nor hear, nor walk:
Rev 9:21 Neither repented they of their murders, nor of their sorceries, nor of their fornication, nor of their thefts.
The 6 trumpets is not the wrath of God upon the world,but warnings to turn to God,which they do not so He allows the man of sin to rule over them.
The 6th trumpet is a war that causes one third of the population of the world to perish,and nuclear weapons are used,which is probably the religion of Islam and the world,but they did not turn to God,so He allowed the man of sin to rule over them,and deceive the world.
This is not the wrath of God,but a making of the world and their war like ways,in which the religion of Islam rebels against the ten horn kingdom,and unified religious system,which is what they want,so they can use the world's power,and nuclear weapons against them,to eliminate their power,for the man of sin does not want any religion that honors a personal God.
Like Hitler told the Germans that going against the Jews would be a healing of the nation,the man of sin will convince the world that going against all who hold the belief in a personal God will be a healing for the world.
There are a lot of Hitler types out there but they have not been stirred up yet,and given the right circumstance they will be crazy too,for that is the way of the flesh.
The people that follow the man of sin will make Hitler look like a toddler.
