I think, like someone said earlier, if we find someone who we love and who will make a good spouse, it is God's intention for us to marry, and "Be fruitful and multiply." There are so many verses in the Bible about marriage and its glory/purposes, but is there as much scripture about being single/independent? (I don't know - I am asking!)
Having said that though, if we do not find the right person I don't think it would seem right to just marry someone for the sake of marriage. In that case it would be better to remain single.
