I apologize if I ignited some contention here. I think the label "wife" is cause for a lot of confusion and I agree with
@The Revolting Man on the assertion that there are no concubines in the body of Christ, and accordingly in the parable of the virgins.
Here's where I am coming from: As many of the more studied men on this forum have pointed out, there is no word for "wife" in the Bible. It's always "Abraham's woman", "David's woman", etc. The word "wife" actually just means "woman" (hence
midwife) but it now (in the last several centuries) has become a social title and carry's a lot of baggage that results directly yet discreetly from a monogamy only culture.
Because the word "wife" has been compromised in this way it is helpful to just set it aside until you are comfortable enough mentally substituting it's synonym: "woman".
All a man's women are indeed "his women", but yet we have within another distinct catagorical term,
concubine, for a woman that belongs to a man, and therefore it must come down to that relationship of belonging.
A concubine is just
not fully his woman, in that
she retains some aspect of her own will apart from his in her heart. (There are many practical reasons she may enter the family without the initial intent of being the patriarch's woman: She may work as a handmaid, she may have come into the family as a captive, or been mercifully taken in from hardship/orphanhood/widowhood, she just is not proven or fully comitted, at least at the present). The concubine
is his physically, but not with all her heart, soul, and strength. Compare this to living out the letter of the law
without it written on your heart. You are holding something back. Outwardly you may appear to belong to the lawgiver, but inside you are not
his. You are a spiritual concubine.
"
Tell me, you who desire to be under the law, do you not listen to the law? For it is written that Abraham had two sons, one by a slave woman and one by a free woman. But the son of the slave was born according to the flesh, while the son of the free woman was born through promise. Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar. Now Hagar is Mount Sinai in Arabia; she corresponds to the present Jerusalem, for she is in slavery with her children. But the Jerusalem above is free, and she is our mother."
Galatians 4:21-26
@The Revolting Man is right, in that there are no concubines among us in the body of Christ:
"
But what does the Scripture say? "Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman.""
Galatians 4:30
This is the inheritance I am getting at, not so much the cultural legalities of their day.
Sarah is free not because she can get up and leave whenever she wants, she is free because she is fully submitted, fully comitted, fully Abraham's woman;
she is not in bondage to anything but her lord. Her son inherits.
But the reality is there
are still concubines among us in modern marriage. If your woman is not yours with heart, soul, and strength, then she is a concubine to you. She is yours in
letter, (literally by license in some cases) but not in spirit. She is holding something back. She is not
yours.
This is why God cares about the content of our hearts so much. Without our hearts fully submitted to him we are not
his. We are then the foolish virgins, obedient to bring our lamp as instructed, but not submissive enough to bring the needed oil. It's the oil that sets apart the anointed for service,
Christos, of which you are a member.
