Revelation 9:1 And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.
2 And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
3 And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power.
4 And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads.
5 And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man.
6 And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them.
As the 5th angel sounds the star that falls from Heaven is Satan and he is given the key to the bottomless pit to release his demons. A great smoke arose out of the pit as if from a great furnace. Now if people do not believe there is a hell they are basically choosing to spend eternity in hell with Satan instead of in Heaven with Christ. The demons that came out of the pit were as locusts, but very large, and they were commanded not to eat any greenery of any kind and could only torment man for 5 months and not kill him. The people to be tormented were only those that were still followers of Satan or the antichrist, any with the mark of God was to be spared the torment, which included the 144000 and the people that have been saved in the tribulation. Some say these three WOE’s are an attempt to get the remaining unbelievers to turn to God. Also here in verse 6 we see that the people being tormented want to die but can not . As we get deeper in to this it gets hard to get all I would like to say in a few lines so again if anyone has any questions or comments if I can I will do my best to answer any questions.
