I'd like to put a disclaimer first. These are just my personal thoughts on the issue, so feel free to disagree. I also don't address anyone personally, we all live in this present day and age and compromise to some degree.
Now, when someone writes an article about female modesty, he usually will point out how the half-dressed women provoke lust in men which inevitably leads to the discussion of how much flesh shown is too much and whether we should teach our sons better self-control instead of teaching our daughters to dress decently.
But as far as I can remember, nobody ever mentioned another aspect of it. What if the Scriptures commands modesty not for the sake of men, or rather, not for their sake only?
Let me explain. There is the famous passage in the NT about women covering their heads in church:
But I would have you know, that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God.
4 Every man praying or prophesying, having his head covered, dishonoureth his head.
5 But every woman that prayeth or prophesieth with her head uncovered dishonoureth her head: for that is even all one as if she were shaven.
6 For if the woman be not covered, let her also be shorn: but if it be a shame for a woman to be shorn or shaven, let her be covered.
7 For a man indeed ought not to cover his head, forasmuch as he is the image and glory of God: but the woman is the glory of the man.
8 For the man is not of the woman: but the woman of the man.
9 Neither was the man created for the woman; but the woman for the man.
10 For this cause ought the woman to have power on her head because of the angels.
Here is what John Gill writes about it in his Bible comments:
F5 understands them of evil angels, and that a woman should cover her head in time of worship, lest they should lust after her; though much rather the reason should be, lest they should irritate and provoke lust in others: but it is better to understand them of good angels, who attend the assemblies of the saints, and observe the air and behaviour of the worshippers; wherefore women should cover their heads with respect to them, and not give offence to those pure spirits, by an indecent appearance...
What if the first interpretation is the correct one? Remember Gen 6 and the story of Nephilim?
So here is my theory. What if female immodesty attracts evil angels and spirits? What if when it becomes generally acceptable in a society that the majority of women run around in what looks like underwear of the times past this society experiences a higher level of demonic activity and rapidly deteriorates? Isn't it what we are witnessing in the West right now? Just compare our modern culture (lack of it) with the early 20th century when most women were covered from head to toes?
If this is the case, then dressing modestly is also very important for the well-being of the woman herself, so that she doesn't attract evil in her own life. She should try and cover herself not so much for men, but first, to preserve her own well-being and second, that of the country as a whole?
Please don't throw stones at me, it's just a theory. However, as they say, sometimes it's better to be safe than sorry!
