TLDR, but I’ve always felt that we’ll be children in heaven. I have no scripture to back it up, but I’ve read where we’ll recognize our spouses, but not have the same attraction to them, or to anyone for that matter. Personally, I think that it would be pretty cool to be a kid again with that sense of awe and wonder towards our Lord that many times is lost as we become adults.
From the article:
**What about age? Our bodies will be youthful and will retain our original sex. Note that youthful does not necessarily mean between 18 and 22! In the Philippians text that began this post, Paul says that our glorified bodies will be conformed to Christs glorified body. When Jesus body rose, He was approximately 33 years old. Elsewhere, St. Paul exhorts Christians to persevere: Until we all meet into the unity of faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the age of the fulness of Christ (Eph 4:13). Hence it would seem that Christs resurrected body is the perfect age.**
So I have always believed that we would be around Christ’s resurrected age.
[[well recognize our spouses, but not have the same attraction to them,]]
I’ve also read that we won’t remember our loved ones back on earth because ‘there will be no sorrow in heaven’ and it would be sorrowful for someone in heaven to know their loved one will go to hell.
Dunno if that’s true or not
There are different types of "attraction" and loves. I think we will love our spouse on a deeper level of appreciation. There will be no sexual urges as that is hormone driven and our body chemistry will be changed. We will have complete control over our emotions (what a change THAT will be!). Time or space will not be a constraint anymore.
Pure as children but as for body, won’t matter. Jesus still has His scars, so that has to be taken into consideration.
