Ecclesiastes hits head on the philosophy of despair and the dark brooding that comes from believing that your plans and actions make no difference in the long-run. Solomon, after spinning that dark philosophy every which way, says that, no, when you do make plans, make plans for action, and then rest confidently without guilt in those pleasures that God allows for you today. Full future details are hidden from you, Solomon says, but what you do for good does matter and it is an inheritance to your children. So make homeschooling plans that don’t expect for a lowest acceptable outcome, but make plans based on a belief that God promises to prosper righteous efforts – because He wants to and has rigged the universe for that purpose. For a great “pump-me up” to fight against any feeling of encroaching darkness, read Gary North’s excellent commentary and explanation of the book of Ecclesiastes (it’s actually part of a larger series on the books of the Bible from a uniquely Economic/Business angle).
