1 Corinthians 7:30-34

And they that weep, as though they wept not; and they that rejoice, as though they rejoiced not; and they that buy, as though they possessed not;

And they that use this world, as not abusing it: for the fashion of this world passeth away.

But I would have you without carefulness. He that is unmarried careth for the things that belong to the Lord, how he may please the Lord:

But he that is married careth for the things that are of the world, how he may please his wife.

There is difference also between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit: but she that is married careth for the things of the world, how she may please her husband.
