She is not afraid of snow for her household, for all her household is clothed with scarlet. (Proverbs 31:21)
We may not know the significance of scarlet material with regard to keeping one warm, but we do know that scarlet clothing was a luxury. Luxury is not necessarily a sign of extravagance, but more a sign of diligence. It is a relevant matter. What may be luxury to one will be commonplace to another. Here in San Diego for example, we have the luxury of beautiful weather; it is commonplace to us, but in other parts of the country good weather is a rarity. Does this make our good weather evil or wrong? By no means does it do so. The same applies to those who do prosper at their endeavors and have comforts and luxuries not common among others. What may be extravagance to one, again, will be the ordinary to another. Therefore do not judge the fruit of prosperity or envy the luxury of another. Instead, see it as a blessing that can be achieved.
