Three unrelated thoughts about failures of memory.
Critics of dispensational teaching frequently insist that it cannot be valid because we do not find it discussed explicitly in the writings of the church fathers or, to the best of our limited knowledge, throughout the next couple of millennia of church history. I have always found that a weak argument, not least because both our knowledge of church history and of the opinions of the church fathers are so fragmentary. In fact, precious truths are far more easily lost than we might think.
Perhaps that’s why Proverbs says, “Buy truth, and do not sell it.” Some things are invaluable.
