"I Have a Dream" speech (excerpt) - August 28, 1963.

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.

"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."
