1 Corinthians 7:35-38

35I say this for your own benefit, not to lay any restraint upon you, but to promote good order and to secure your undivided devotion to the Lord. 36If anyone thinks that he is not behaving properly toward his betrothed, if his passions are strong, and it has to be, let him do as he wishes: let them marry—it is no sin. 37But whoever is firmly established in his heart, being under no necessity but having his desire under control, and has determined this in his heart, to keep her as his betrothed, he will do well. 38So then he who marries his betrothed does well, and he who refrains from marriage will do even better.
