Btw, I am aware that my fear seems irrational, but this doesn't make it go away.
I simply cannot imagine something I don't know. I also couldn't imagine what it feels like to be a cat.
Seems like some people here don't seem to be able to comprehend something like this.
Bingo! Obviously what you are talking about is going over some heads, while some get it.
Let us consider the replies up to this point in the order they were posted:
1. "This is why Christ said, "leave all the burdens to me and let tomorrow worry about tomorrow". This is good advice.
2. "I know some people say they don't want Heaven to be a big choir.": I love music, but I think variety will be the spice of heaven.
3. "this is all crazy-talk. You cannot seriously be doubting that God does not know what we would find fulfilling; or believe that he would prepare an eternity of boredom for his people." This is nothing but a pejorative rant, missing your point completely.
4. "Well, think of it this way: It's a better option than hell,": So true, so true!
5. "you are not talking like a believer in Jesus. your comments are preposterous. it's impossible for a Christian not to enjoy heaven. you do not speak like a born again Christian either." This nothing but a judgmental rant, completely beside the point.
6. "However, as it is written: “What no
eye has seen, what no ear
has heard, and what no human mind
has conceived”— the things God
has prepared for those who love him". This is a very good reply.
7. "This is the only appropriate reaction really.

". Not at all constructive or thoughtful.
8. "The New Jerusalem is a place where the saints start afresh and remember nothing prior to that." This is debatable but moves the discussion forward. It is part of your point that I have also pondered: Will the lessons learned on Earth be completed in Heaven?
9. "It's not possible to be in heaven and not enjoy it for all eternity. But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
1 Cor 2:9 (KJV) And the ransomed of the LORD shall return, and come to Zion with songs and everlasting joy upon their heads: they shall obtain joy and gladness, and sorrow and sighing shall flee away.
Isaiah 35:10 (KJV) Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us,
Eph 3:20". Another good reply that builds on #6.
10. "After my Mom and Dad died in 2024, I read 2 books on Heaven... Heaven is anything but mundane and boring. People are actively busy. They are seen walking with their families. They work for God in things they enjoy. People are happy. No suffering. The beauty. The worship. The illustrations of what Christ did, a panorama of the Cross. The throne room. Jesus in the midst of the people. Appointments with the King. Libraries of books with our names written. People in Heaven are allowed to see happy moments on earth, babies born, Revivals where people are saved *see
Hebrews 12:1. In any event, it was a great peace to me to see what my folks were experiencing." Personal visions are rather problematic, but encouraging nevertheless!
11. "It says it's beyond your current imagining So that'd mean it's beyond your current doubts & fears too things have the potential to be decent here on earth, that also should be a type of proof for OP that such things are possible Desirable even We believe we'll be restored after death, where else would we want to go but be with God?" Yep, alternate reality is beyond imagining, but not beyond possibility.
12. "I commend you on introducing a novel topic, and although I have not worried about it, I have wondered about it. My wondering and pondering has concluded with these two realizations: 1. It is impossible for finite human brains to conceive of alternative reality in detail or other than by way of analogy, which is why Jesus employed figurative language including parables. 2. We can begin to imagine enjoying heaven for at least a few minutes if we think about how much fun it would be to explore earth if we could do so with friends safely and leisurely. In truth, we may have so much fun that we would be happy being bored for awhile, and if we ever decided heaven was undesirable, Satan showed that there is an express elevator that only goes down." This obviously is the best reply so far. :^)
13. "Did it ever occur to you that you are demeaning God with this thread?": Obviously this thread is beyond his comprehension.
14. "In the Old Testament we read in several passages of Scripture where several people were rewarded not just things they needed but also many things they desired. Even the Bible claims that God knows the [(desires of our hearts)]. Everyone In Heaven that gave up treasures on earth to build treasures in Heaven will eternally have their desires rewarded unto them. This means you will absolutely love Heaven. It's not only where our Lord God and Savior will be but also where our Rewards will be." This reply is positive but problematic to think human desires are better than God's rewards.
