1 Corinthians 7:30

“And they that weep, as though they wept not, etc.] They that weep for troubles and crosses, things adverse and afflicting in a marriage state, for the loss of wives or children, should express their sorrow in such a manner and degree, as if they wept not; not that the apostle here introduces and establishes a stoical apathy, and would have persons show no manner of concern for these things; but he directs to a moderate use of sorrow, to such a degree as not to hinder and divert from the exercises of piety and religion: and they that rejoice, as though they rejoiced not; such who are blessed with great prosperity, and with whom everything goes well; they have married wives, and have children,…”

“they that weep . . . wept not--(Compare Co2 6:10). they that buy . . . possessed not--(Compare Isa 24:1-2). Christ specifies as the condemning sin of the men of Sodom not merely their open profligacy, but that "they bought, they sold," &c., as men whose all was in this world (Luk 17:28). "Possessed" in the Greek implies a holding fast of a possession; this the Christian will not do, for his "enduring substance" is elsewhere (Heb 10:34).”

“And they that weep - They who are afflicted. As though they wept not - Restraining and moderating their grief by the hope of the life to come. “The general idea in all these expressions is, that in whatever situation Christians are, they should be dead to the world, and not improperly affected by passing events.” It is impossible for human nature not to feel when persecuted, maligned, slandered, or when near earthly friends are taken away. But religion will calm the troubled spirit; pour oil on the agitated waves; light up a smile in the midst of tears; cause the beams of a calm and lovely morning to rise on the anxious heart; silence the commotions of the agitated soul, and produce joy even…”

“And they that weep, as if they wept not - "Though sorrowful, yet always rejoicing." They that rejoice, as if they rejoiced not - Tempering their joy with godly fear. They that buy, as if they possessed not - Knowing themselves to be only stewards, not proprietors. 1 Corinthians 7:31”

“that weep: Psa 30:5, Psa 126:5, Psa 126:6; Ecc 3:4; Isa 25:8, Isa 30:19; Luk 6:21, Luk 6:25, Luk 16:25; Joh 16:22; Rev 7:17, Rev 18:7 1 Corinthians 7:31”
