1 Corinthians 6:9-11
Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God.
Being any of those things pretty much wrecks society.
Do I think God thinks sex is bad? Nope. But if you are stepping out on your family, that doesn’t end well.
If sex wasn’t fun, people would not make babies. Duh.
