1 Corinthians 7:40

“But she is happier if she so abide, etc.] That is, a widow, in an unmarried state; which is to be understood not of the happiness of another world, but of this: the apostle’s meaning is, that she would be more free from cares, and less liable to trouble, would live with more peace and quietness, and be more at leisure to serve the Lord, second marriages oftentimes proving more disagreeable than the first; but in this the apostle only gives his opinion, enjoins nothing by way of command, or in an authoritative manner: and therefore adds, after my judgment: according to his sense of things, and agreeably to the advice he had before given to unmarried persons, whether virgins or widows, such a…”

“happier-- (Co1 7:1, Co1 7:28, Co1 7:34-35). 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 Co1 7:25, "my judgment" or opinion. Think does not imply doubt, but often a matter of well-grounded assurance (Joh 5:39). Next: 1 Corinthians Chapter 8”

“If she so abide - If she remain a widow even if she could be married to a Christian. After my judgment - In my opinion; 1 Corinthians 7:25. And I think also that I have the Spirit of God - Macknight and others suppose that this phrase implies entire certainty; and that Paul means to affirm that in this he was clear that he was under the influence of inspiration. He appeals for the use of the term (δωκῶ dōkō) to Mark 10:32; Luke 8:18; 1 Corinthians 4:9; 1 Corinthians 8:2; 1 Corinthians 11:16; Hebrews 4:1, etc. But the word does not usually express absolute certainty. It implies a doubt; though there may be a strong persuasion or conviction; or the best judgment which the mind can form in…”

“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, Co1 2:16, Co1 14:37, and the other. Co2 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 Co1 10:12. Next: 1 Corinthians Chapter 8”

“she: Co1 7:1, Co1 7:8, Co1 7:26, Co1 7:35 I think: Rather, "I judge (or consider) also that I have the Spirit of God;" for δοκειν is frequently used to express not what is doubtful, but what is true and certain. Co1 7:25, Co1 9:1-3, Co1 14:36, Co1 14:37; Co2 10:8-10, Co2 12:11; Th1 4:8; Pe2 3:15, Pe2 3:16 Next: 1 Corinthians Chapter 8”
