In First Corinthians 7, Paul addresses whether we should marry or remain single and the question comes up because of persecution.
When persecution arrives, it is better if one has not formed a family,
“But this I say, brethren, the time is short, so that from now on even those who have wives should be as though they had none, those who weep as though they did not weep, those who rejoice as though they did not rejoice, those who buy as though they did not possess, and those who use this world as not misusing it. For the form of this world is passing away” (1 Corinthians 7:29-31).
However, he did stress that it is not wrong to marry, and of course, it is not wrong to remain single.
Christians may suffer for their Christianity, and that should help them decide whether to marry, because Christianity is greater than family.
