"While thus occupied, as I journeyed to Damascus with authority and commission from the chief priests, at midday, O king, along the road I saw a light from heaven, brighter than the sun, shining around me and those who journeyed with me.  And when we all had fallen to the ground, I heard a voice speaking to me and saying in the Hebrew language, ‘Saul, Saul, why are you persecuting Me? It is hard for you to kick against the goads.’  So I said, ‘Who are You, Lord?’ And He said, 'I am Jesus, whom you are persecuting.'"

Ac 26:12-15   (NKJV)
