This is not to say that those who are not yet married should be discouraged by that. For regardless of whether you find marriage or not on the physical level, this is still true. It has been my privilege many times to marry people, and I have to deal with certain state laws. Marriage is not the product of human society. It is not something that people invented after they began to live together.
Marriage goes back to the very dawn of the human race.
Marriage is an absolutely integral part of human life, and physical marriage, between man and wife, is simply a picture of a deeper relationship that is true of everyone. This principle is discussed in Romans 7, as the apostle Paul opens that great argument with an illustration of a married woman. While she is married, she is bound by the law to her husband. And if, while she is married to him, she falls in love with another man, she will gain the stigma of an adulteress, that is, she will expose herself as breaking the basic law of life. But if the husband dies, then she is free to be married to another man.
