1 Corinthians 7:36-37

If a man thinks he is not doing the right thing with the girl he is engaged to, if she is almost past the best age to marry and he feels he should marry her, he should do what he wants. They should get married. It is no sin. But if a man is sure in his mind that there is no need for marriage, and has his own desires under control, and has decided not to marry the one to whom he is engaged, he is doing the right thing.
