I hate stories like this. They try to quantify the immeasurable and use it as an indictment.
My favorite religious parable.
A bible study group pondered the meaning of God's utterance, "I shall refine you like silver". They had the gist of it but they weren't familiar with the exact science behind silver refinement so one of them said she would ask a family friend who was a jeweler.
The next business day the young lady went to the firnd and made her inquiry, "How do you refine silver?" The process was simple enough: you hold it over a flame. Unsettling, but it made sense of tribulations bettering a person.
"But," the silversmith interjected before the young lady's uneasy acceptance could set in. "I have to be very precise and exact as to how I do it.
"If I set the unrefined silver too far from the flame the impurities will not leave it entirely giving a tarnished product. But if I set it too close the sample will curdle and spoil."
"So too if I fail to leave it in the fire long enough or hold it there too long."
"Then how do you know when the silver is finally ready?" the young lady asked.
"Oh, that's the easiest part," the jeweler answered smiling.
"I can see myself in it."
I cannot imagine man can make himself anything but a sinner. The are sinners in pews and saints in gutters. Only God knows which is which but no saint ever slipped through his fingers. Nice? Mean? Stop asking about the other guy and worry about yourself. What would God see if he looked at you?
