^^ Best answer. Worry about being with God, then let God take care of the rest.
Think about guys or girls who are dealt a bad hand in life as far as finances, life situation, looks, social skills (big big big one), etc., rendering them unable to enter into a relationship and get married or ever find a partner. Some people will die as unwilling virgins. Meanwhile everybody else gets to enjoy companionship and sex with their partner. The outcast who wanted a partner (especially if it’s someone specific) is locked out forever, and they’re just out of luck. This is far more common than society likes to admit, so the problem continues and has increased with the Millenial generation.
So they die and in the afterlife are just forever excluded from something everybody else got to enjoy because humans have said there’s not going to be “any use for it” or “impossible” (because God is definitely limited by what humans say is impossible) in the afterlife anyway? Doesn’t sound very heavenly. The argument is also made that we won’t need sex or relationships because we’ll have direct access to God and that should be enough. This is the greatest “spiritual” joy one can imagine, certainly, but then what? What about other aspects of existence? We’re in some kind of “nirvana” forever like in Buddhism, a “oneness” where we don’t exist anymore? There’s a reason God created woman for man, and animals, etc.
Jesus also says, in Revelation, that after he destroys this world, he will create a perfect one where humanity will be restored, and sadness, evil, etc. will be abolished from existence.
So I would assume that basic activities that humans enjoy like eating, drinking, having sex, sleeping, entering into relationships, having children, etc. will be a part of the New Earth too.
