In 1 Corinthians 7, the Apostle Paul addresses those who are unmarried.  His words are challenging and clearly spell out God's will for singles: 

"But I want you to be without care. He who is unmarried cares for the things of the Lord--how he may please the Lord. But he who is married cares about the things of the world--how he may please his wife. There is a difference between a wife and a virgin. The unmarried woman cares about the things of the Lord, that she may be holy both in body and in spirit ... And this I say for your own profit, not that I may put a leash on you, but for what is proper, and that you may serve the Lord without distraction." -- (1 Cor. 7:32-35).

In the margin of my Bible I have written, "As a single woman, may I serve You, Jesus, with all my body and spirit."  You see, no one who has been redeemed by Christ has the right to be footloose and fancy-free. 

Singleness, whether for a few years or a lifetime, is not a time to be without responsibility but a time to serve Christ wholeheartedly and full time, regardless of our vocation. 

The season of singleness is not a time in limbo, waiting for the right partner to come along so we can get on with our lives.  Those years of singleness provide an incredible and unique opportunity to be devoted to Christ and His kingdom in a way that married men and women simply do not have the freedom to pursue.

Those of us who are single face a danger of becoming self-absorbed.  Free from the constraints of family life, it is all too easy to become preoccupied with fulfilling our own social needs or consumed with our jobs or with making money.
