God prescribed a way for women to be protected and provided for by men especially during times of war, famine and disease when men are being killed off. His answer was polygamy. That my friend is one of the big reasons God gave men polygynous desires. In fact if we practiced Levirate marriage as found in the Old Testament(Deuteronomy 25:5-10) if a man’s brother was killed in war or some other way he would marry his brother’s wife to care for her and raise up an heir for his brother’s estate. And no there was no prohibition of if he was married he could not do this if did not do it it would be a shame to him.
So yes during times of relative peace as the world has seen for several decades where we are not losing men by the millions we seem to question God’s wisdom. But I can tell you if another world war broke out and millions of men were being killed over several years the truth of what I am telling you would be very real.
But let’s leave war and disease taking out all the men and talk about why polygamy is needed even in times of peace like we have today.
Even if there was an exact ratio of 1/1 males and females there is a great possibility that many men will not want to marry. In fact a lot of women talk about this today- “Where are all the guys that want to marry?” That is a different topic for another post. But I can tell you for a fact when I was going through my divorce they told us that divorced men had a far easier chance of getting married and often got married faster than the divorced or widowed women. It is just harder for divorced or widowed women to get married again especially if they have children for a variety of reasons.
Now if polygamy were legal it would solve this problem by allowing wealthier men to come along and have multiple wives and be able to care for them and their children.
