The meaning of the devotion 'Unexpected Joy'

This devotion comes from a devotional story.
A sinful man used to pray before an image like this. One day, while praying, he saw that Christ's wounds were bleeding, accusing him of his sins. After crying and asking for forgiveness, Christ forgave him through the intercession of the Virgin. Since then, she has been invoked to obtain sudden help in dangers, illnesses, misfortunes, and distress.

It is a very popular devotion in Russia since the 18th century.
