As an "agnostic" or bad/weak Christian, I known that Christianity warns others about sensual things like eating, sex, attractiveness, a lot of this stuff. But, do you think God meant to create the system we see as if those are always inherently evil or sinful?
Jesus also even said in Matthew 22:30 (there was also another iteration elsewhere in the bible) that "they will neither marry, nor be given in marriage..." so it seems that Jesus said we won't be married or have a similar kind of intimacy with the opposite sex of any kind at all in Heaven. That is one thing that made me feel even repulsed and one part that "helped" my faith slowly wither until the point today.
I don't feel like I can completely accept Jesus or God anymore. I used to be more spiritual or at least tried to be when I was younger, I thought that I was going to be able to have a partner, but the narrative about not being with someone who I can look at with physical passion, be naked with, and have an exclusive intimacy that I could've missed seeing on earth (seems that there is a two-tiered system in place) have made me disillusioned. I also became more disillusioned because I was born at the time where my generation will be the one alive to see everything become really awful and then it would just end.
That is kind of where it stems from, why do you believe it is fair too? That other people, Christian and non-Christian alike got to acquire something that seems to be denied to a significant group of people who desire it but are denied it, either because God said no or the world makes it hard or difficult in some way?
What about when God said we will see whatever we would desire? Is desiring a partner of the opposite sex to be with somehow unclean to God or has become unclean in his eyes? At least a lot of Christians seem to have a subconscious belief thinking so.
I want to close here for now.
