Taking a deep breath, she thought, "I must be able to see at least one quality of God in this sales clerk before I speak."
So she prayed. And she listened for something, anything good about this clerk. Lots came to mind, but they were more faults than positive qualities derived from God, universal Good. And then she thought, "Wait a minute. She breathes, therefore she expresses Life!"
She began to think about the presence of divine Life. She realized that where Life, God, is, every quality of God is present and expressed. That one thought, better than the thoughts of injustice and anger she was holding onto before, completely inspired her.
Then the clerk suddenly noticed her and said, "May I help you?"
Paul wrote in a letter to the Romans, "Since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse. " (1:20)
Science and Health with Key to the Scriptures explains, "As mortals gain more correct views of God and man, multitudinous objects of creation, which before were invisible, will become visible." (Mary Baker Eddy, p. 264:13)
I have observed - time and time again - that all it takes is a pause and a prayer to redirect thought to the spiritual fact of man's goodness as the reflection of God in order to take the steam out of the kindling furnace of injustice. One better thought can do a lot to bring more of God's goodness into full view.
