Tim Challies asks what disposable time plus disposable income ought to equal for Christians.
His answer ("opportunity") isn't terrible, but it misses the mark. He nearly gets there - his wording in unpacking what "opportunity" means mentions "stewardship". But stewardship isn't primarily about opportunity; it is about responsibility. The Biblical answer is "responsibility": "Everyone to whom much was given, of him much will be required, and from him to whom they entrusted much, they will demand the more." - Luke 12:48. When the Master gives you ten talents, and not just five or one, he holds you responsible for ten talents, not just five or one. That thought ought to make a lot of us as Western Christians at this juncture not so much be excited at the opportunity, as tremble at the waste.
