Why was the world and later Sodom & Gomorra destroyed
The Flood
Genesis 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.
Genesis 6:6 And it repented the LORD that he had made man on the earth, and it grieved him at his heart.
Genesis 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.
Genesis 6:8 But Noah found grace in the eyes of the LORD.
Sodom & Gomorra
Genesis 18:20 And the LORD said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous;
Genesis 18:21 I will go down now, and see whether they have done altogether according to the cry of it, which is come unto me; and if not, I will know.
Genesis 19:13 For we will destroy this place, because the cry of them is waxen great before the face of the LORD; and the LORD hath sent us to destroy it.
Jeremiah 23:14 I have seen also in the prophets of Jerusalem an horrible thing: they commit adultery, and walk in lies: they strengthen also the hands of evildoers, that none doth return from his wickedness: they are all of them unto me as Sodom , and the inhabitants thereof as Gomorrah .
Lamentations 4:6 For the punishment of the iniquity of the daughter of my people is greater than the punishment of the sin of Sodom , that was overthrown as in a moment, and no hands stayed on her.
Ezekiel 16:49 Behold, this was the iniquity of thy sister Sodom, pride, fulness of bread, and abundance of idleness was in her and in her daughters, neither did she strengthen the hand of the poor and needy.
2 Peter 2:6 And turning the cities of Sodom and Gomorrha into ashes condemned them with an overthrow, making them an ensample unto those that after should live ungodly;
Jude 1:7 Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
I see no where in the Bible where it says God destroyed man because he was no longer human or because of his DNA. The reason has been and always will be because of sin or one could say serving Satan which is the same thing. By taking the Mark in the tribulation you would have committed yourself to serving Satan.
Some can’t receive this and that’s OK. All I am doing is sharing what the Bible says.
