I believe I addressed this three years ago when this thread was new.
If I owned a business or a farm, I would allocate a generous but prudent amount for a livelihood for myself and my family as remuneration for operating the business and assuming the inherent risk of owning it.
I wouldn’t tithe the remainder of the profits. I would plow them all back into the business to pay for overhead, employee payroll, expansion, etc.
But I don’t see this “cost of doing business” as the functional equivalent of the taxes I pay as a citizen. I don’t pay them out of fear of consequences for not doing it. I pay them out of the expectation that I’ll receive value directly benefitting my life, health and well-being and that of my family.
I pay them because it is the most efficient way I know of to fund the essentials that I need. That is to say, I cannot afford to operate my own private police force or fire department or to build and maintain my own streets and highways or on my own to protect myself and my family from foreign invaders. I don’t have the wherewithal to educate my own children as efficiently as can be done at the local public school or on my own to ensure that the food and other products I buy are safe and wholesome. If someone violates my God-given rights, I don’t have the capability on my own to track him down and administer justice fairly and efficiently.
I cant do this stuff by myself. So I pool my resources with those of my fellow citizens, and, together, through economy of scale, we get it accomplished in a mutually beneficial way. It’s not a perfect system, but it works well enough from day to day.
Paying taxes is the mechanism by which I participate in this pooling of resources to meet common needs. I receive value from this participation, so I willingly include the amount I spend for taxes as part of the personal increase I tithe when discharging my debt to the Lord.
