I saw your points but I do not think they are as valid as you believe them to be. What you are doing is assuming things that are not clearly presented in the text. I will admit that this woman is doing somethings outside of the home but there is nothing in the text of Proverbs 31 that even insinuates that she is doing what many women today are doing (working 40 hour work weeks outside the home). Yet Titus 2 seems to be clear that the majority of the woman's time is to be in or at the home. I believe this creates a problem for your position. If more time is spent outside the home, away from the kids than is spent working...how is a woman being obedient to Titus 2? There has yet to be an answer to that question and it is one I really would like to hear on this particular topic, especially from the women.
I do agree that a 40 hour work week is not ideal for women and that their home should be their primary ministry. However in today's culture, in today's world of excess taxes and high cost of living, many women DO need to work and thus we have a conundrum. I'm not even speaking of women who want the second Lexus or anything but those families for whom not having the second income means that they have no home for whatever reason. With one family I know, the husband was a professional commercial plumber and he was hit in the arm with a large pipe, breaking it in 5 places. He had surgery and it's now a year later and he cannot use that arm well enough to continue in his former job. Disability was not enough to support the family so finally his wife had to go out to get a job while he stayed home with the kids. He has tried to find other work but he's not trained in anything else and having his arm almost useless, he just cannot get anything. So the wife works full time now. It's not ideal but it's much better than going on welfare or whatever. Sometimes life just happens, you know?
