I think that that is a fascinating idea.
How would you go about starting and doing that?
I'm willing to try something in that line as part of a broader overarching construct.
For instance, if it costs $4,000/child/ year at a traditional brick and mortar-type school, then over that child’s lifetime he and his parents would donate that amount ( and **more**) to the fund. The student ( as well as other sympathetic Christians) could bequeath money to the fund in their wills, and assign a portion of life insurance policies.
As the fund grew, it would eventually become a pure gift and not a loan.
However,,,I think we should abandon the idea of traditional brick and mortar schools. With today’s technology it would be possible to have many group homeschools, or “one room school houses” meeting in members’ homes, with churches ( and their Christian teachers) merely acting as facilitators. The cost could and should be far, far less than $4,000 a year.
