There's no need to panic, John. I was only trying to help you see this at a level that you feel comfortable dealing with. I cannot read your mind so I didn't know where to start from. I rarely respond to bullies - if you try it again I won't reply.
I apologise for the duplicate postings. I haven't figured a way round that. Either it doesn't post the message atall or does so numerous times!
Anyway, here goes: Every scripture has to be understood within the context of the entire Bible. If you take Ryan's initial sentence out of context it could be assumed that God declared:
'I will not allow people to live forever,' for the first time. This isn't the case. He bestowed that particular curse way before when Adam and Eve violated His commands. This brought Adamic sin onto all unrighteous mankind. Therefore the scripture which Ryan quoted has, logically, to be a reminder of what was already going on at the time. Adam and Eve were designed to live forever in paradisiacal conditions. God has plans to restore those conditions and fill the planet with obedient people after Armageddon. So, it is not true to say that he will never allow folk to live forever again, and indeed, it doesn't say that, but that's what some people may gather if they are unfamiliar with the bigger picture. I couldn't stand around and let something so crucial go over anyone's head without doing a disservice to God. I prefer the two Bibles I quoted from to Ryan's example. The passage in the New World Translation is especially helpful because it supports the fact that obedient mankind will get everlasting life on earth. The word 'indefinitely' conveys the understanding of an undetermined time. You could paraphrase it thus: 'My spirit shall not act towards man for an undetermined time' or: 'I will not allow people to have everlasting life until the time that I determine.'
I do hope this helps you, John.
Now, as for the second sentence,
'from now on they will live no longer than one hundred and twenty years', I'd like to repeat what I said initially. This is all tied in with the effect that the Nephalim had over people in those days. As a consequence of the Adamic sin, Adam's descendants failed to live forever - the point being that this was already happening. It wouldn't be surprising to discover that God restricted the lives of the pre-flood rebels more severely than the likes of Seth, Jared, and those who still found favor with god. If you have a look at Genesis 6:3 you will see that it begins with, 'After that...' After what? After the sons of God (fallen angels) took the daughters of men for their wives... then God pronounced the 120 year maximum lifespan. But the Bible doesn't say it affected anyone else after that. The Adamic sin did, yes, which is why the few survivors of the Flood and each generation ever since did not and do not live forever. Also, the 120 year restriction will not apply to post-Armageddon survivors. I know that's not made clear in Genesis 6:3 but God couldn't have everything in the Bible put on one page, now could he?
This message has taken me about fifty years to compose and I hope that it has shed a little light on things for you. I'm not here to try and win points. I originally replied to Ryan's query because he seemed to genuinely want answers. It would be great to think that you read this in the same manner that I wrote it. I'm not sure who your god is (Satan maybe? yes/no???) but there's nothing to stop you praying to Almighty God if you want more answers. I've often found it amazing as to how He finds ways of opening my eyes.
