Albert Barnes Commentary 1 Corinthians 7:28

"But shouldest thou marry, thou hast not sinned; and if a virgin marry, she hath not sinned. Yet such shall have tribulation in the flesh: and I would spare you." — 1 Corinthians 7:28 (ASV)

Thou hast not sinned. There is no express command of God on this subject. The counsel which I give is mere advice, and it may be observed or not, as you shall judge best. Marriage is honourable and lawful; and though there may be circumstances where it is advisable not to enter into this relation, yet there is no law that prohibits it.

The same advice would be proper now if it were a time of persecution; or if a man is poor and cannot support a family; or if he already has a dependent mother and sisters to be supported by him, it would be well to follow the advice of Paul.

So also, when the cares of a family would take up a man's time and efforts—and when, if not for these, he might give himself to a missionary life—the voice of wisdom may be in accordance with that of Paul, so that a man may be free from these cares and may give himself with more undivided interest and more successful toil to the salvation of man.

Such shall have trouble in the flesh. They shall have anxiety, care, solicitude, and trials. Days of persecution are coming, and you may be led to the stake; and in those fiery trials, your families may be torn asunder, and some put to death. Or you may be poor, oppressed, and driven from your homes, and made wanderers and exiles for the sake of your religion.

But I spare you. I will not dwell on the melancholy theme. I will not pain your hearts by describing the woes that shall ensue. I will not do anything to deter you from acting as you deem right. If you choose to marry, it is lawful; and I will not embitter your joys and harrow your feelings by the description of your future difficulties and trials. The word flesh here denotes outward circumstances, in contrast to the mind. They might have peace of mind, for religion would provide that; but they would be exposed to poverty, persecution, and calamity.
