No, it's probably almost the reverse. Many people are afraid of commitments and relationships, and many people are eager to stretch their wings and do their own thing. And then maybe later, when they've traveled the world and done lots of things that satisfied them, then maybe they will lock in to somebody...maybe.
So there's a lot of the independence and a lot of desire to satisfy their own immediate desires, which has nothing to do with what Paul was talking about, namely, increased devotion to the Lord.
How would you challenge a Christian who has these selfish desires?
I would say that singleness is a gift for as long as you have it. Some people God means to have it for a lifetime, and some people God means to have it for a season. But while you have it, consult the Scriptures to see how you can maximize the freedoms of singleness for the glory of Christ, because there are advantages to being married, and there are advantages to singleness when it comes to serving Jesus.
And I would just encourage Christian single people to ask, "For this chapter in my life, while I am single, what is it about my singleness that could make me especially fruitful for Christ?" And then I would encourage them to give themselves to that.
