What a person keeps doing when nothing is wrong is the whole of what they will have when everything is.
Acting on what might have happened rather than on what has is the mark of a standard that runs ahead of events. Treating a private thought in someone else's heart as a real debt before God sets the state a man lives in, the state sets the emotion he rises with, and the emotion gets him out of bed early for work nobody asked him to do.
A practice kept for years, long after the reason for it has gone abstract, is quietly assembling the man who will meet the day it was never designed for. Without those years he meets the worst hour of his life with whatever he happens to feel that morning, and feeling is thin material to carry that weight.
