One group of folks in the New Testament who had an extremely high opinion of themselves were the Pharisees. These religious leaders were good at seeing the sin in others, but somehow oblivious to their own sins. And so one day when a Pharisee named Simon invited Jesus to have dinner at his house, it provided a teachable moment of such significance that it ended up being recorded in the Bible.
You see, this event in the earthly ministry of Jesus actually helps to diagnose "the Pharisee in all of us."
"When a woman who had lived a sinful life in that town learned that Jesus was eating at the Pharisee's house, she brought an alabaster jar of perfume, and as she stood behind Him at His feet weeping, she began to wet His feet with her tears. Then she wiped them with her hair, kissed them and poured perfume on them." (Luke 7:37,38).
