1 Corinthians 7:28
But and if thou marry, thou hast not sinned; and if a virgin marry, she hath not sinned. Nevertheless such shall have trouble in the flesh: but I spare you. (1 Corinthians 7:28)
I spare you.
Rather, “I would spare you.” As to the meaning of this clause there is a difference of opinion among commentators. Two interpretations are given: (1) “I will not enlarge on these evils, in order to save you from the pain of hearing about them.” (2) “I am giving you this instruction in order to save you from these troubles.” The latter is the more probable.
Trouble in the flesh.
 The cares of husband, wife, and children and other duties of married life produce special perplexity in times of persecution and tribulation (see Matt. 24:19; cf. Luke 23:28-30). The words “in the flesh” point to the earthly life with all its interests, here indicating particularly domestic life, with its many cares about food, clothing, and the protection of all family possessions. In the days of persecution to come upon the church some believers would be imprisoned, tortured, and put to death. Families would be divided and the members driven into exile for the sake of their faith. Under such circumstances, says Paul, it would be better to remain single.
Thou hast not sinned.
The matter of marriage is left to each individual to decide for himself, according to his own inclination and need. The advice Paul gives in this chapter is intended to be a safe guide to all who face the question of marriage, particularly under adverse circumstances. But when all has been said, the ultimate decision rests in the hands of each individual. Each may choose the course that suits his own particular situation, knowing that both marriage and the single state are acceptable to God. There are conditions when it seems unwise to marry. But celibacy is not urged upon anyone; it is to be entirely a matter of individual decision.
