But I tell you that anyone who divorces his wife forces her to be guilty of adultery. The only reason for a man to divorce his wife is if she has sexual relations with another man. And anyone who marries that divorced woman is guilty of adultery.
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.
A woman must stay with her husband as long as he lives. But if her husband dies, she is free to marry any man she wants, but she must marry another believer.
Marriage should be honored by everyone, and husband and wife should keep their marriage pure. God will judge as guilty those who take part in sexual sins.
