1 Corinthians 7:33

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:

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.

And this I speak for your own profit; not that I may cast a snare upon you, but for that which is comely, and that ye may attend upon the Lord without distraction.
