A great illustration. Right down my alley.
A professor of religious studies informed his students on the last day of the term that not one of them had demonstrated a satisfactory understanding of Christianity. He ordered them to take out a blank sheet of paper and, in one minute, explain the theological essence of Jesus’ teachings.
The students panicked. Some wrote nothing, others wrote and erased, wrote and erased. When the professor ordered them to bring their papers forward, some were shaking, others were angry, a few were sure they’d nailed it.
The students stared in horror as the professor flipped through the sheets, muttering, “No…wrong…not even close…absurd…”
He then stood, and with a red marker scribbled an “A” on each of their papers.
“It’s grace,”he said. “Have a good summer.”
