But she is happier if she so abide, after my judgment: and I think also that I have the Spirit of God.

People's New Testament

7:40 But she is happier if she so abide, after my judgment. In his judgment, and in the conditions then prevailing, she will consult her happiness by remaining a widow. It is not only his judgment, but the Spirit seems to point the same lesson. 1Ti 5:14 might be supposed to conflict with this, but it does not, when we remember that Paul's advice here is due to prevailing circumstances. The question of marriage or remarriage is one of prudential considerations.

Wesley's Notes

7:40 I also - As well as any of you. Have the Spirit of God - Teaching me all things This does not imply any doubt; but the strongest certainty of it, together with a reproof of them for calling it in question. Whoever, therefore, would conclude from hence, that St. Paul was not certain he had the Spirit of Christ, neither understands the true import of the words, nor considers how expressly he lays claim to the Spirit, both in this epistle, 1Co 2:16, 14:37, and the other. 2Co 13:3. Indeed, it may be doubted whether the word here and elsewhere translated think, does not always imply the fullest and strongest assurance. See 1Cor 10:12.

Jamieson-Fausset-Brown Bible Commentary

40. happier-(1Co 7:1, 28, 34, 35).

I think also-"I also think"; just as you Corinthians and your teachers think much of your opinions, so I also give my opinion by inspiration; so in 1Co 7:25, "my judgment" or opinion. Think does not imply doubt, but often a matter of well-grounded assurance (Joh 5:39).

Matthew Henry's Concise Commentary

7:36-40 The apostle is thought to give advice here about the disposal of children in marriage. In this view, the general meaning is plain. Children should seek and follow the directions of their parents as to marriage. And parents should consult their children's wishes; and not reckon they have power to do with them, and dictate just as they please, without reason. The whole is closed with advice to widows. Second marriages are not unlawful, so that it is kept in mind, to marry in the Lord. In our choice of relations, and change of conditions, we should always be guided by the fear of God, and the laws of God, and act in dependence on the providence of God. Change of condition ought only to be made after careful consideration, and on probable grounds, that it will be to advantage in our spiritual concerns.

Matthew Henry's Whole Bible Commentary

Verses 39-40

The whole is here closed up with advice to widows: As long as the husband liveth the wife is bound by the law, confined to one husband, and bound to continue and cohabit with him. Note, The marriage-contract is for life; death only can annul the bond. But, the husband being dead, she is at liberty to marry whom she will. There is no limitation by God's law to be married only for such a number of times. It is certain, from this passage, that second marriages are not unlawful; for then the widow could not be at liberty to marry whom she pleased, nor to marry a second time at all. But the apostle asserts she has such a liberty, when her husband is dead, only with a limitation that she marry in the Lord. In our choice of relations, and change of conditions, we should always have an eye to God. Note, Marriages are likely to have God's blessing only when they are made in the Lord, when persons are guided by the fear of God, and the laws of God, and act in dependence on the providence of God, in the change and choice of a mate-when they can look up to God, and sincerely seek his direction, and humbly hope for his blessing upon their conduct. But she is happier, says the apostle, if she so abide (that is, continue a widow) in my judgment; and I think I have the Spirit of God, v. 40. At this juncture, at least, if not ordinarily, it will be much more for the peace and quiet of such, and give them less hindrance in the service of God, to continue unmarried. And this, he tells them, was by inspiration of the Spirit. "Whatever your false apostles may think of me, I think, and have reason to know, that I have the Spirit of God." Note, Change of condition in marriage is so important a matter that it ought not to be made but upon due deliberation, after careful consideration of circumstances, and upon very probable grounds, at least, that it will be a change to advantage in our spiritual concerns.
