I wish that all were as I myself am. But each has his own special gift from God, one of one kind and one of another. To the unmarried and the widows I say that it is good for them to remain single, as I am.
1 Corinthians 7:7-8
Wife, how do you know whether you will save your husband? Husband, how do you know whether you will save your wife? Only, let every one lead the life which the Lord has assigned to him, and in which God has called him. This is my rule in all the churches
1 Corinthians 7:16-17
Now concerning the unmarried, I have no command of the Lord, but I give my opinion as one who by the Lord’s mercy is trustworthy. I think that in view of the present distress it is well for a person to remain as he is. Are you bound to a wife? Do not seek to be free. Are you free from a wife? Do not seek marriage. But if you marry, you do not sin, and if a girl marries she does not sin. Yet those who marry will have worldly troubles, and I would spare you that. I mean, brethren, the appointed time has grown very short; from now on, let those who have wives live as though they had none, and those who mourn as though they were not mourning, and those who rejoice as though they were not rejoicing, and those who buy as though they had no goods, and those who deal with the world as though they had no dealings with it. For the form of this world is passing away. I want you to be free from anxieties. The unmarried man is anxious about the affairs of the Lord, how to please the Lord; but the married man is anxious about worldly affairs, how to please his wife, and his interests are divided. And the unmarried woman or girl is anxious about the affairs of the Lord, how to be holy in body and spirit; but the married woman is anxious about worldly affairs, how to please her husband. I 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. If any one 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. But 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. So that he who marries his betrothed does well; and he who refrains from marriage will do better. A wife is bound to her husband as long as he lives. If the husband dies, she is free to be married to whom she wishes, only in the Lord. But in my judgment she is happier if she remains as she is. And I think that I too have the Spirit of God.
1 Corinthians 7:25-40
