Gen 6:1 And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,
Gen 6:2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
Gen 6:3 And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
Gen 6:4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
Gen 6:5 And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
Gen 6:6 And it repented the LORD that he had made man on the earth, and it grieved him at his heart.
Gen 6:7 And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
I have not studied this too much,but I believe when it refers to the sons of God,that it is spiritual beings,and not speaking of the sons of Seth,for if they were godly men,why did it produce such ungodly people to where they were evil continually,especially if the men were in charge and were godly,and if they were godly why would they mingle with those who are ungodly,and how would it produce men of old,men of reknown.
But with evil spirits it would make sense,but I do not believe that the evil spirits themselves had sex with the women,for there could be no offspring from that union,but that the evil spirits possessed the men,and had sex with the women through the men,and that is why it caused such wicked people,for it was the evil spirits affecting mankind,to where they eventually all became evil continuously.
This will happen again when God gives the world a certain amount of time to have their way,and cause all people that do not love Him to follow the beast kingdom,and then He can end this sin business on earth.
Mat 24:36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
Mat 24:37 But as the days of Noe were, so shall also the coming of the Son of man be.
Mat 24:38 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,
Mat 24:39 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
Jesus said that the end time will be like the days of Noah,and points out that it will be business as usual and not heeding the saints preaching the end time and get right with God,like they did not heed Noah and get right with God,but it could be that they did not heed being influenced by a devil,so the end time being like the days of Noah might relate to what happened before the flood,the evil spirits influencing mankind until all who do not love God are continually evil like the days of Noah,and that is why they follow the beast kingdom.
Rev 9:13 And the sixth angel sounded, and I heard a voice from the four horns of the golden altar which is before God,
Rev 9:14 Saying to the sixth angel which had the trumpet, Loose the four angels which are bound in the great river Euphrates.
Rev 9:15 And the four angels were loosed, which were prepared for an hour, and a day, and a month, and a year, for to slay the third part of men.
Rev 9:16 And the number of the army of the horsemen were two hundred thousand thousand: and I heard the number of them.
Rev 9:17 And thus I saw the horses in the vision, and them that sat on them, having breastplates of fire, and of jacinth, and brimstone: and the heads of the horses were as the heads of lions; and out of their mouths issued fire and smoke and brimstone.
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 are 6 disasters that happen on earth that the world knows about,and are 6 warnings to the world to turn to God,but after the 6th trumpet they do not turn to God,but keep trying to solve their own problems despite all the problems that occur on earth,so after the 6th trumpet God allows the man of sin,beast,to rule over them,and deceive all who do not love Him.
Rev 12:7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
Rev 12:8 And prevailed not; neither was their place found any more in heaven.
Rev 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
Rev 12:10 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
Rev 12:11 And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
Rev 12:12 Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
Rev 12:13 And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child.
Rev 12:14 And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
Rev 12:15 And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood.
Rev 12:16 And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth.
Rev 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
When the world does not turn to God to help them refusing to believe the truth,God will allow the man of sin,beast,to rule over them,and war breaks out in heaven,and the devils are cast to earth,and deceive all who do not love God to follow the beast kingdom.
Rev 18:1 And after these things I saw another angel come down from heaven, having great power; and the earth was lightened with his glory.
Rev 18:2 And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird.
2Th 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2Th 2:2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
2Th 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
2Th 2:4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
2Th 2:5 Remember ye not, that, when I was yet with you, I told you these things?
2Th 2:6 And now ye know what withholdeth that he might be revealed in his time.
2Th 2:7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
2Th 2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
2Th 2:9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
2Th 2:10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
2Th 2:11 And for this cause God shall send them strong delusion, that they should believe a lie:
2Th 2:12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
The earth becomes the holding cell of the devils,and they will deceive all people who do not love God,strong delusion,a delusion they cannot snap out of.
It will be like the days of Noah when the evil spirits influenced mankind to where they were continually evil,for when the devils deceive all people who do not love God to follow the beast,and they take the mark of the beast,then repentance,and salvation is no longer available to them,and then they have the nature of a devil,and their human will is gone for they forfeited their human will and they will only behave like the devil would behave,and they will be continually evil.
Like the evil spirits that influenced mankind before the flood,and they became continually evil,the evil spirits will again influence mankind at the beast kingdom,and they will be continually evil,in which no actions will come from their human will,no resistance,for they will only act as the devil would act.
They thought that taking the mark was a good thing,and felt good about it,elated,the beast would establish a kingdom that would never topple,would always survive,and prosper,and he would restore all the occult powers that mankind lost through the ages to them,and they would be greater than ever,like Satan tempted Eve to cause her to believe if she ate the fruit that she would be greater than the current position that God put her in.
But when they took the mark their being changed drastically.All elation dissipated,any feelings of good,and well being slipped away,and they felt cold,and empty,bitter,and hateful,for now they have the nature of a devil,and now they know how the devil feels with the anger,and hatefulness,and bitterness,and emptiness,and coldness,and they only act like a devil,with no human will of their own,and they cannot resist,resistance is futile like the borg from Star Trek,for they are completely controlled by a devil,as the man of sin.
In Genesis 6,I believe it is evil spirits that influenced mankind to the point of them being continually evil,for it makes the best sense,and I do not believe that it is referring to the people of Seth as the sons of God,because of the description of the condition of mankind that was so terrible that God wiped them out.
Only by the influencing of the evil spirits could they be so wicked and terrible,and right now Satan is on a leash,but when God allows the world to have their way to cause all who do not love Him to follow the beast kingdom,the leash is taken off him,and the devils will wreck havoc with the world,but for now he is restrained from having that much control.
When the world says Peace and safety,then sudden destruction comes upon them,and they shall not escape,and that starts the deception upon the world to cause the people that do not love God to follow the beast kingdom,thinking that it is the best operation of the world,which will start with the ten horn kingdom,the world split in to ten sections with a leader in each section,but they will fail at obtaining peace on earth,especially the 6th trumpet,and the world turns to the beast.
But Paul said the elect will not be deceived when they say Peace and safety,knowing it is not the operation of God,and Jesus said He will deliver all those in the truth from the temptation that shall come upon all the world,to try all them that dwell upon the earth.
It is the point of decision for the whole world,which the elect will be delivered from that temptation,and the world will not be forced,but it is a temptation for the rest of the world,and for three and one half years the world can still be saved,so the saints reaching out to the world to tell them now about this decision point when they say Peace and safety might be to the saving of their soul,for they might believe then when it happens,and not follow the world,but get right with Christ.
2Th 2:6 And now ye know what withholdeth that he might be revealed in his time.
2Th 2:7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
2Th 2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
2Th 2:9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
2Th 2:10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
The evil spirits are retrained now from having too much influence in the world,but that restrain will be lifted,and then it will be like the days of Noah for the evil spirits will influence all who do not love God,and they will be continually evil.
That is how I understand it,for it seems to make sense.
