1 Corinthians 7:36-38

But if a man thinks that he’s treating his fiancée improperly and will inevitably give in to his passion, let him marry her as he wishes. It is not a sin. But if he has decided firmly not to marry and there is no urgency and he can control his passion, he does well not to marry. So the person who marries his fiancée does well, and the person who doesn’t marry does even better.
