Let’s look at the verses you posted Job 1:6 “Now there was a day when the sons of God came to present themselves before the Lord, and Satan also came among them.
Job 2:1 “Again there was a day when the sons of God came to present themselves before the Lord, and Satan came also among them to present himself before the Lord.”
38:7 “When the morning stars sang together, And all the sons of God shouted for joy?”
These are clearly speaking of angels, let also look at Lucifer as one of the sons of God.
Isaiah 14:12 “How you are fallen from heaven, O Lucifer, son of the morning!”
Unfortunately that’s the only Scripture on Lucifer, but I will agree he was one of the sons of God, Once he became satan he gave that up. Look at the verses in Job, “and satan came in among them” this separates him from the sons of God. 2:1 further separates him from the sons of God by adding that, “to present himself” Lucifer was part of the sons of God, but satan isn’t because of his fall. I agree the sons of God are angels that haven’t left their position of authority or have not sinned. That’s not the only reason I don’t interpret the sons of God in Genesis 6:2, 4 as angel. Because we are only talking about 11 verses that uses the term sons of God and they are all used for beings that are in fellowship with God.
What did God say at creation about procreation.
Genesis 1:24-25 “Then God said, “Let the earth bring forth the living creature according to its kind: cattle and creeping thing and beast of the earth, each according to its kind”; and it was so. And God made the beast of the earth according to its kind, cattle according to its kind, and everything that creeps on the earth according to its kind. And God saw that it was good.”
Let’s look at what does Jesus says about angels and procreation.
Luke 20:35-36 “But those who are counted worthy to attain that age, and the resurrection from the dead, neither marry nor are given in marriage; nor can they die anymore, for they are equal to the angels and are sons of God, being sons of the resurrection.”
Matthew 22:29-30 “Jesus answered and said to them, “You are mistaken, not knowing the Scriptures nor the power of God. For in the resurrection they neither marry nor are given in marriage, but are like angels of God in heaven.”
What does Paul say about the earthly body and the heavenly body.
1 Corinthians 15:39-40 “For not all flesh is the same, but there is one kind for humans, another for animals, another for birds, and another for fish.There are heavenly bodies and earthly bodies, but the glory of the heavenly is of one kind, and the glory of the earthly is of another.”
It’s clear from Genesis 6:2 that the sons of God married.
Procreation is after it’s own kind, Jesus said that in the resurrection we will be like the angel. We will have heavenly bodies that can not have sex. It’s clear that the sons of God had sex with the women of earth, because there were children born to that union. What does Paul say about heavenly bodies and earthly bodies. That they are not the same kind, which would mean they can’t procreate according to the creation account. Just like animals can’t procreate with birds or birds with fish, because they are not of the same kind. Jesus said the angels do not marry or are they given in marriage, He said that after Genesis 6:2, I’m going to believe Jesus that angels do not marry or have ever been married. There are three witnesses that they don’t procreate. After the same kind, they are not given in marriage and heavenly bodies are different then earthly bodies
Someone mentioned mules, a donkey and a horse are from the same family or kind.
Here are the verses used to support the idea that these are angel that sinned. II Peter 2:4-6 “For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment; and spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly;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;”
They say that “and spared not the old world” are linked together with the angels that are reserved for judgement. The semicolon gives more pause with the and, so all of these are being used as examples of judgement. They further try to link them together in, Jude 1:6-7
“And the angels who did not stay within their own position of authority, but left their proper dwelling, he has kept in eternal chains under gloomy darkness until the judgment of the great day—just as Sodom and Gomorrah and the surrounding cities, which likewise indulged in sexual immorality and pursued unnatural desire,serve as an example by undergoing a punishment of eternal fire.”
They skip the period to end the sentence and run it together with “as Sodom and Gomorrha” then skip over, “and the cities about them” and go into “like manner giving themselves over to fornication” and “going after strange flesh”. When there is a clear separation of the angels and Sodom and Gorrohhra. It seems to me that “Sodom and Gomorrah, and the cities about them” are the ones that gave themselves to fornication and went after strange flesh, which seems to mean beastiality. Jude clarifies why the angels were judged, because they left their “position of authority” and “proper dwelling”. They completely leave out verse 5 of Jude, which is how the example of judgement starts out. Where they make another mistake is the are saying that these angels fornicated with the women of the earth. How did they fornicate when they were married to the women? Watch the video, you'll see Chuck using this argument to support his interpretation of Genesis 6:2, 4 as angels, because they fornicated, which never happened, because the text says that they married the women.
Jude 1:5 “Now I want to remind you, although you once fully knew it, that Jesus, who saved a people out of the land of Egypt, afterward destroyed those who did not believe.”
Here’s how I interpret Genesis 6:4 “There were giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men and they bore children to them. Those were the mighty men who were of old, men of renown.”
When were the giants on the earth, “in those days” and “also afterward”, what days “when the sons of God came in to the daughters of men”, they had children who were these children? “Those were the mighty men who were of old, men of renown.” Not the giants.
There’s my Scriptural bases for not believing that the sons of God in Genesis 6:2 , 4 are not angels.
Here’s something interesting Romans 10:13 “For “whoever calls on the name of the Lord shall be saved.”
Genesis 4:26 “And as for Seth, to him also a son was born; and he named him Enosh. Then men began to call on the name of the Lord.”
Since you brought up "false witness" I went a watched one of Chuck's videos on this subject. This is what he said about Genesis 6, "understanding this chapter is foundational to understanding most of the OT, as well as prophecy, it's not just the mystical chapters of early Genesis it is very foundational to understanding the rest of the Bible."
