I asked: How can those who are immortal be guided to the fountains of waters of life?
EndOfMysteries answered:You will notice in both the old testament and new testament one thing identical to the fountains/waters of life. That they come from under the temple. In the Old testament, this they come from under the temple, one flows to the dead sea and brings life to the sea. Also trees grow on both sides and their leafs give healing to the nations. Jesus says that YOU, your BODY is the temple, and inside you a spring will bubble and give life. Then in Revelation, it appears a spiritual Jerusalem with waters flowing from it.
Okay, I'm not really sure how this answers the question. Can you possibly rephrase with a one-sentence answer that makes it clear exactly what you are trying to say?
I asked: 'How will they 'no longer hunger or thirst or experience the heat from the sun' anymore when they have HEAVENLY, SPIRITUAL, IMMORTAL BODIES'
Reply: As for how will they no longer hunger, experience the heat from the sun, your question alone answered that, if they are spiritual they do not need to eat and the heat from the sun would not harm them. If they are immortal, there is no death.
The scripture says 'God will wipe out every tear from their eyes'. This is implying that in the present (the vision that John is presently seeing) things such as tears still exist. Pain, mourning, scorching heat from the sun, still exist. The scripture says that these things will be no more. If we interpret the great crowd as inhabiting heaven, they have already received their immortal bodies, and these things do not exist (presently). Therefore, it cannot be said that such things will be down away with, when the interpretation requires that they already have been eliminated. I hope this helps. This is why the interpretation of the great crowd being in heaven poses so many issues that directly contradict the following verses that follow the vision.
I didn't disagree with anything you said about 1 Corinthians so there's nothing I can really respond to about that.
What is interesting, is the idea that flesh will live forever and never die, atleast once, seems to be spoken in Is 28:14-15, speaking about those who made a covenant with death, that they would never die, how it's a false teaching.
Isaiah 28:14-15 "Therefore hear the word of Jehovah, YOU braggarts, YOU rulers of this people who are in Jerusalem: 15 Because YOU men have said: “We have concluded a covenant with Death; and with She′ol we have effected a vision; the overflowing flash flood, in case it should pass through, will not come to us, for we have made a lie our refuge and in falsehood we have concealed ourselves.."
The people in Jerusalem did not believe that they would live forever and not die. They simply believed that Assyria would not come through Jerusalem and that they would be protected by Egypt. Again, I'm not really getting the flux of your argument.
