As designed by our Creator, marriage is to be the commitment of a man and woman to each other for a lifetime. But, co-habitation is the denial of commitment. While marriage is to be for a lifetime, co-habitation is usually brief and the breakup hurtful.
Some non-marrieds have a sense of satisfaction with their single life and see its advantages as a biblical alternative to marriage. The Apostle Paul says that God has “gifted” some to remain single and find special fulfillment and spiritual fruitfulness as satisfied singles!
However, if you are not satisfied being single, then the Apostle says it is better for you to marry than to be vulnerable to the sexual tension and temptations of our society!
