Marriage is still a good idea because it is God’s idea. He created it. He designed it. He established it and defined its parameters. Contrary to much contemporary thought and teaching, marriage is not a human concept. Mankind did not simply dream up marriage somewhere along the line as a convenient way of handling relationships and responsi- bilities between men and women or dealing with childbearing and parent- ing issues. Marriage is of divine origin.
In order to happy in life we all have to marry. Without marry our is not fulfill. Marry is a part of our life.
Not only to marry but a right person.
I think it's a matter of personal preference.
I married at the age of 25 and it was perfect timing. I wouldn't want to have married any sooner or later. I also wouldn't want to change who I married or the fact that I married.
But I am open-minded. There is a chance that out of the 7,442,000,000+ people living on earth, one or two of them (maybe more?) might experience more happiness and fulfillment by remaining single as opposed to getting married.
You might want to consider that a possibility too.
Marriage was a good idea for me when I was 24 - 25 and that is why I got married when I was 25 (on my 25th birthday). But it would have been a very bad idea for me to get married at the age of 17 - 18 (I was unstable at that age and immature).
So in summary, it doesn't matter if God created the concept of marriage or if man did. Sometimes it's a good idea to get married and sometimes it's not.
