I just know that in heaven, we will experience joy and contentment that cannot be explained for eternity. We will not be tired of it because we will be free from our human limits of emotions and suffering and the shear greatness of God’s presence. The unknown is very scary but I personally have more comfort in knowing good things lie ahead. Even if that means eternity.
Physical body just means something that looks like your physical body. Not necessarily a body that can die. Option 4 is pretty much the concept that heaven isn’t a realm like ours and doesn’t have any sort of “physical” manifestation at all, just your consciousness in a state of pure bliss in eternity. No experiences at all.
heaven is so confusing to me. i don’t think anyone would want eternal life, but that’s what heaven is. the justification for suffering on earth is that it makes life more meaningful, but doesn’t that mean that heaven would be meaningless if it’s just constant pleasure? and if i am getting a new body, name, and basically identity, would i still even be “me”? if i had the choice i would rather go to hell or cease to exist.
It doesn't mean you'll be given a strangers body or anything like that, it'll be your own just "renewed". Scientifically I believe this to mean a body that is not affected by cellular degeneration and mutation. But obviously I don't know for sure. Additionally, this doesn't change who you are, your soul and personality aren't dependent on your physical body's appearance or legal name so it's illogical to assume you would be "stripped of your identity".
Refer to my other responses for the answer to your question. The point of heaven is a place without suffering, correct, but it’s also where we’ll be to live with God physically. Because we will be free from mortality and without sin, we’ll actually be able to be in His full glory.
This might be worldly, but I like my name. I don’t want it to change even if a deity tells me to. It’s probably symbolic or something but I dunno. I am who I am, and if I’m destined for heaven then I’ll go there. But I’d like to keep my identity, and my name is part of that.
