The truth is this: The march of Providence is so slow and our desires so impatient; the work of progress is so immense and our means of aiding it so feeble; the life of humanity is so long, that of the individual so brief, that we often see only the ebb of the advancing wave and are thus discouraged. It is history that teaches us to hope. Robert E. Lee This was written well over 100 years ago. IMO, is is a universal and timeless truth.
