Matthew Henry Commentary 1 Corinthians 7:36-40

"But if any man thinketh that he behaveth himself unseemly toward his virgin [daughter], if she be past the flower of her age, and if need so requireth, let him do what he will; he sinneth not; let them marry. But he that standeth stedfast in his heart, having no necessity, but hath power as touching in his own heart, to keep his own virgin [daughter], shall do well. So then both he that giveth his own virgin [daughter] in marriage doeth well; and he that giveth her not in marriage shall do better. A wife is bound for so long time as her husband liveth; but if the husband be dead, she is free to be married to whom she will; only in the Lord. But she is happier if she abide as she is, after my judgment: and I think that I also have the Spirit of God." — 1 Corinthians 7:36-40 (ASV)

The apostle is thought to give advice here about arranging the marriages of children. In this view, the general meaning is clear. Children should seek and follow the guidance of their parents regarding marriage. Parents should consult their children's wishes and not assume they have the power to deal with them and dictate just as they please, without reason.

The entire section concludes with advice to widows. Second marriages are not unlawful, provided it is kept in mind to marry in the Lord.

In our choice of relationships and changes in life circumstances, we should always be guided by the fear of God, the laws of God, and act in dependence on the providence of God. Any change of condition should only be made after careful consideration and on reasonable grounds that it will be advantageous for our spiritual concerns.
