The wise and godly woman here knows the taste of success. When it says that she "senses" her gain is good - God uses the word for tasting something. She works hard, which we see consistently in the previous verses. But more than that, she tastes that what she is doing it good. The things that she sells to the merchants brings her gain - it helps her to earn money. She knows and tastes the success that hard work brings. It is important that people experience the fruit of their labor. I am not one who believes in the economic systems of socialism or communism. Those two systems tout a false idea of community goods that are shared by all. The problem is that such systems kill the benefits of hard work and labor for the individual. In the end, the collective works only as hard as they want to - and since they receive nothing but the same allotment for their labors - they are not motivated to excell at them. The result of tasing the fruit of your labors will be far less labors. When we are allowed to taste that sweet fruit, we are motivated to labor harder, smarter, wiser for the good of our own benefit - and by that for the good of our family and others around us.
This godly woman knows that her gain is good. Here we have another confrontation with the current thoughts on economics. In our world gain is bad! How dare Capitalists relish the fact that they are making a profit. We wrongly call them evil - yet it is their "so-called profit that allows so many others to enjoy benefits. This godly lady knew in her heart that hard work would yield good things - and would bless her - bless her family - bless others who bought them - and eventually would bless her community. When governments try to "equalize" the playing field - what they mean is that they are going to promise everyone the same outcome - because that is what they say is fair. What is amazing is that they want an equal misery for the masses - but for themselves luxury. Every socialist and communist leader has evidenced the sin nature. They talk a certain egalitarianism among others - but they themselves will have the most. They will have the best of everything. What they deliver to the people is equal poverty and misery.
It is self-interest that will drive men and women to their best efforts. They must receive some reward for hard labor - and once they taste this fruit - they will want more. This results in hard work - work ethic as it is called. This woman knows that. Because she tastes that her gain is good - she works hard. She labors into the night as her lamp can testify. She stretches out her hands to make clothing - which is what the terms distaff and spiindle indicate. This is because she is working toward her own self-interest. In this case that means her own clothing - the clothing of her family - and clothing that can be sold to others to earn more money for the welfare of her home. This is the kind of work God encourages - and blesses. May He give us wisdom to reject the false philosophies that promote powerful government officials who speak of equality and egalitarianism - but who only deliver a corporate misery to the masses as they live high on the hog themselves. May we instead see the value of hard work, frugality, and wisdom in taking what God gives us and using it for the benefit of our families. The fascinating thing about this kind of life is that as families (Which are the basic unit of society in God's economy) multiply with these views, a village, city, region, and even nation is blessed and prosperous as a result.
