God said to Adam, “It is not good for the man to be alone; I will make him a helper suitable for him” (Gen 2:18). And many quote this to promote the joys of holy matrimony and to push others to getting hitched (rightfully so).
However, the single brothers and sisters respond this way: “Yes, I understand that it is not good for a man to be alone. But does that make my singleness something that is bad?”
Not at all! It is ALSO good for a man or woman to be “alone” (using that term loosely).
We’ve heard it said that married people can glorify God in ways that singles cannot, but John Piper observes that the opposite it also true. Singles can glorify God in ways that married people cannot. If you are single or know anyone that is, please listen to this short sound clip from Piper. It may help you realize that singleness is not the “death sentence” that some make it out to be. And it may also show that the single individual is not as alone as he may think.
The Contenders 
I love teaching on the topic of relationship and also on singleness. When we think that each one of us might be single in our lives (in the event our spouse dies, etc), it ought to make us think biblically how we handle singleness even if we are married.
