Paul the Apostle actually says that being single is ultimately better

[Honest]

He later mentions the fate of the sexually immoral.  

1 Corinthians 6:9-10: “Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God.” 

Always funny when people use those verses in 1 Cor 6 as proof that certain kinds of people are doomed to hell. They assume that the "kingdom of God" must mean a future heaven, when the Bible makes claims to the contrary:

For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost.
Romans 14:17

20 And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation:
21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
Luke 17:20-21

But that doesn't fit our theology and can't be used to scare/control people, so we'll continue to pretend that it's referring to heaven
