Is Polygamy Unwise?
According to a survey, 10% of the participants (100 votes) said polygamy is not sinful, but is unwise as it is not God's ideal of one man and one woman for life.

But in a patriarchal society where there are more men than women, where it was next to impossible for women to provide for themselves and be protected, it seems much wiser to allow for polygamy than to allow women to go hungry or resort to prostitution.As for as monogamy being the biblical ideal of one man and one woman for life, that is highly debatable.

First, we are not living in an ideal world. We are fallen creatures living in a fallen world. Perhaps, had Adam and Eve not ate the forbidden fruit, perhaps monogamy would have been the norm. We can only guess. However, in the New Heaven and the New Earth, which is a perfectly ideal setting, marriage as we know it will not even exist (See Matthew 22:30).
