1 Corinthians 7:26 (NLT)
Because of the present crisis, I think it is best to remain as you are. ... (28) those who get married at this time will have troubles, and I am trying to spare you those problems.

1 Corinthians 7:29 (NLT)
But let me say this, dear brothers and sisters: The time that remains is very short. ...

1 Corinthians 7:31 (NLT)
Those who use the things of the world should not become attached to them. For this world as we know it will soon pass away.

- Paul is not against marriage, but I think he seems to sense that huge changes are near at hand. Whether he is specifically referring to the immenant return of Christ, or to political upheavals and the pursecutions of Christians by emperor Nero or perhaps both, isn't clear.
