"I'll tell you, I've seen the lightning flash. I've heard the thunder roll. I felt sin-breakers dashing, trying to conquer my soul. But I heard the voice of Jesus saying still to fight on .. Jesus reminds us that the good life combines the toughness of the serpent and the tenderness of the dove."
Delivered to over 250,000 supporters from the steps of the Lincoln Memorial .. a defining moment of the civil rights movement and among the most iconic speeches in American history.
