Road to Damascus

This everyday expression indicates a major turning point in a person’s life.
The phrase refers to the story in the New Testament of St. Paul’s conversion to Christianity.

In Chapter 9 of the Acts of the Apostles, whilst on the Road to Damascus, Paul the Apostle had a vision which made him convert to Christianity and change his life.
In the vision, Jesus appeared and asked why was he was persecuting him, after which he was struck blind for three days and had to be guided into the city.
According to the Acts, Ananias of Damascus arrived, telling him he had been sent by Jesus to restore his sight and baptise him.
From then on Paul went into all the synagogues preaching that Jesus was the Son of God.
