The woman sacrifices herself and her womb to her husband, to the Quiverfull movement and to God.
I've known some families in this movement and the women do not consider carrying pregnancies any kind of a 'sacrifice'. Since they see children as a blessing, they feel their womb is blessed with the gift of a child EVERYTIME they are given a pregnancy.
They also fail to follow through on their logic. Every one of the quiverfull families have a committed father in the relationship. If the woman is sacrificing, then it would stand to reason the husband of the wife and the father of these children is sacrificing something as well. Perhaps his entire work life in order to support his children? Hmm, but I guess the 'sacrifice' of the father matters little next to the martydom of the mother.

The man, just as well as the woman, is submitting that God is the head of everything in their lives, including fertility. The trust relationship with God is between both people in the home, not just the woman. BOTH parties put trust in God. I wouldn't expect DUmmies to understand this concept of submission of both partners because in their world, unless you are of Islam of course, paternalism is under every rock. It doesn't occur to them that there are very happy and fulfilled families who are part of this lifestyle.
I've never understood their thinking where a woman bossing around a guy and expecting him to bow to her every whim while she withholdes relations with him is somehow a noble, headstrong, confident woman and the man is just a great guy, doing what he has to do...that's an acceptable sacrifice in their eyes is some wimp living under the burden of a bossy, feminist female. However, a woman submitting to the will of God and her husband is some kind of a downtrodden waif who needs rescuing and to have her turned around to be a big, bossy feminist too.

What gets me is they never see that in most situations, the relationships are carried on in MUTUAL agreement and that their bias is just that: a biased worldview of marriage in general and very devoted Christian marriages in particular. I say if a man can choose to be a big ***** next to his feminist wife, then why can't a woman choose to be submissive to her husband?
