Acts 9:3-6

As he traveled he approached Damascus, and suddenly a light from heaven flashed around him [displaying the glory and majesty of Christ]; and he fell to the ground and heard a voice [from heaven] saying to him, “Saul, Saul, why are you persecuting and oppressing Me?” And Saul said, “Who are You, Lord?” And He answered, “I am Jesus whom you are persecuting, now get up and go into the city, and you will be told what you must do.”
