We didn't contribute anything other than what we collected in field service.
Once we realized out that we were contributing our time and resources, and had a special wardrobe just for meetings and service, we did the math and calculated that the amount of our non-monetary contributions were over $10,000 a year.
Both hubby and I can work any day of the week and between the two of us "contributed" (ie, lost) a half-days' worth of wages for every Saturday and Sunday we spent doing "God's Will". Not to mention the mid-week travelling and time spent to attend the Tuesday and Thursday night meetings.
Then there's the gas, mileage, insurance and vehicle depreciation accrued while driving all over the territory while in service.
Factor in next whatever it costs to purchase and for dry-cleaning suits and dresses that are solely 'meeting clothes'.
It doesn't take much to figure out that the money that people spend toward the mundane "invisible" contributions they make to support the WTS could easily allow a family to afford a downpayment on a home or a better car or extracurricular activities for the kids.
That was "contribution" enough for us.
Love, Scully
