The virtuous woman is a woman of strength. Though the weaker vessel, she is made strong by wisdom, grace and fear of God. Perhaps one reason for the rarity of a virtuous woman is that she is seldom sought. Too often the search is made for accomplishments and external qualities rather than for godly internal worth.
Most women think they'll never attain what is laid down in Scripture. But, it's like the Christian walk - if we look at those around us, we tend to get discouraged. We're all at a different levels in our Christian walk. God sees you right where you are and that's where you need to get up and get going from. When more light (knowledge) is given, more (faith) is required. We don't get in bad shape over night, so we shouldn't expect to fix everything overnight.
A woman is subject to her husband, but she can still go directly to God to ask anything she needs or desires and get it as quickly as if she were a man. God hears the prayers of a godly woman as quickly as he hears the prayers of a godly man. If the Lord Jesus Christ, God Himself, submitted to the authority of the Father, it is no shame or dishonor for a woman to be under authority.
