Because there`s no sex for fun only in heaven? I got the impression also that the devil, lucifer, just pretends to be your friend anyways, he turns his back on everyone
When people talk about "choosing hell" it tends to be in a much more subtle way than that.
Imagine a narcissist who lives their entire life choosing themselves over and over and over, the end result of that is hell. Not because one is "sent to hell" for being a narcissist, but because hell is, in a sense, what it looks like to choose oneself--in a very ultimate way.
If God's purpose and will for the universe is to bring all things toward redemption in Christ, and that means the healing and renewal of all creation, the restoration of human beings to perfect communion with God and one another and with the rest of all creation--then what does it look like when a person chooses
not that?
Jesus tells a parable of a wedding feast, but the invited guests refuse to come, so the invitation goes out to others who receive proper wedding guest attire, and they all come and enjoy the feast. The parable has a couple layers of meaning, but one of those layers is one is either joining in on the party, or they are not. Those who refuse to come and enjoy the feast, those who choose to remain outside of the party, are there by their own refusale.
If "heaven" is the party, then not joining in on the party is "hell". It's the absence of the feast, the absence of the party, it's
absence,
lack.
Heaven isn't a party for the "cool people", it's a party for everyone, including all the world's rejects and losers who have been excluded by the "cool people"--it's the "cool people" who choose not to come, so they are left outside, miserable, by their own choice.
C.S. Lewis once put it this way, "It's not that God sends anyone to hell, it's that there is something in us that will become hell unless it is nipped in the bud."
We can compare it to refusing to come to a party. Or we can speak of it as the result of denying our own God-given humanity. In the Apocalypse/Revelation, St. John calls it "the second death". What does it look like to reject life and choose death so completely that it's as though it is a death beyond death? That's the sobering language John uses in the Revelation, a second death, a death beyond death--a sort of
total rejection of life.
When all that is lively, good, beautiful, and life-giving is removed--what's left? Almost nothing at all.
