I haven’t read all the many posts, so if this is redundant, ignore it.
For a long time, I have thought of working this way:
-People will not readily part with their money, as a general rule.
-If they are willing to part with it, it is because they want or need the good or service offered.
-My business is a professional service. My hobby is raising cattle.
People pay for both.
-If my service is something for which people are willing to pay, or if they want to nourish themselves or others with my cattle and are willing to pay for that, then I am doing something good for them. Otherwise they wouldn’t pay for it. How they use it is up to their own consciences. In my mind, no higher earthly compliment could be paid to me than to have someone so value my services or my cattle that they are willing to pay money for them.
In some other job, someone other than the end user pays me. If my boss is willing to pay me money for my services, that is a high compliment, and a sure sign that my efforts result in things people (the customers) want or need.
We can’t look at jobs and know for sure what the good/ill balance is from the products or services. We just can’t know. I guess, for example, an IPod is a needless extravagence for many. But yet, it might bring cheer to someone who really needs that. It might help a tired motorist stay awake. Oil companies might be concerning for the environment, but right now, that oil keeps people from freezing to death or starving because food can’t be transported without it. That oil is what gets family members to the bedside of a dying relative, or lights the operating room where that relative might be saved. The mining company that digs up the land for mineral provides the metal for the life-saving surgeon’s scalpel, the wire that carries electricity to the respirator and the child’s night light, and the machines that help a working mother have a little time for rest.
The Old Testament, particularly, honors work, and makes it clear that it is not to be disdained. We can’t always know the results of our work, anymore than we can always know what long-term effect one word or failure to say one word might have on another. it is not given to us to know all those things. But we certainly can know that God has promised that our work would be of value in His eyes, and that it is our function here to do it. And we know that if someone is willing to pay us for it, it is deemed a good thing by someone.
