The Road To Damascus
In Acts 9, Saul converted to Christianity while walking on the road to Damascus.
Meanwhile, Saul was still breathing out murderous threats against the Lord’s disciples. He went to the high priest and asked him for letters to the synagogues in Damascus, so that if he found any there who belonged to the Way, whether men or women, he might take them as prisoners to Jerusalem. As he neared Damascus on his journey, suddenly a light from heaven flashed around him. He fell to the ground and heard a voice say to him, “Saul, Saul, why do you persecute me?””
The road to Damascus is used to refer to any large-scale change of feeling.
