You're right, Morgan - I now see that you didn't take “man” to mean “man” at large, but to literally mean only “Adam,” the first man and son of God. My bad for not realizing you were saying something so obviously daft and in error.
“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” (Genesis 6:3 KJV).
If God was addressing Adam, He would have said so. There is nothing whatsoever to connect this verse to Adam, not in itself or the context. The context is Noah's time, his 500th year, and what God was planning to do with mankind because of the wickedness described. By this point, Adam had already been dead for over 600 years.
Furthermore, the word translated as “man” always means “man,” and never Adam specifically. Just 4 verses after the Scripture you quoted, is an excellent example that definitively refutes your twisted translation:
“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 I repent that I have made them. But Noah found grace in the eyes of the LORD” (Genesis 6:7-8 MKJV).
Aside from the glaring issue of a timeline that doesn't fit, how could God be talking about destroying Adam when it's clear that He proceeded to destroy “man,” all men, from the face of the earth?
If you weren't so proud of your credentials, Morgan, I would be ashamed to have to explain such a simple matter to a man of your age and presumed experience. But there is no fool like an old fool, hardened off in pride and ignorance, and it's my pleasure in the Lord Jesus Christ to point this out to you, since it's His Name you're taking in vain and defiling.
As for the false doctrines on your page, I gave you our writings. Look for yourself, if you're interested, and have at it if you think you can prove us and the Scriptures wrong.
