So perhaps this is the legacy of my generation to the younger generation of today. It is the achievement of some level of “social integration” at the level of the heart as well as the mind that has made Barack Obama’s candidacy possible. Despite residual racism, particularly in older generations, his young supporters represent the real possibility that Dr. King’s dream of a time when people are not judged by the color of their skin, but by the content of their character, is finally at hand.

Tonight I won't be at Mile High Stadium. (I'd hoped to be one of the ten Obama contributors invited, but alas...) But I'll be watching, and over my heart I will wear both those buttons, from August 28, 1963, and for the fierce urgency of today.

Postscript: Speaking of the American Promise, here is what Barack Obama said to end his acceptance speech before 84,000 people at Mile High stadium in Denver:

And it is that promise that forty five years ago today, brought Americans from every corner of this land to stand together on a Mall in Washington, before Lincoln's Memorial, and hear a young preacher from Georgia speak of his dream.

The men and women who gathered there could've heard many things. They could've heard words of anger and discord. They could've been told to succumb to the fear and frustration of so many dreams deferred. But what the people heard instead - people of every creed and color, from every walk of life - is that in America, our destiny is inextricably linked. That together, our dreams can be one.

"We cannot walk alone," the preacher cried. "And as we walk, we must make the pledge that we shall always march ahead. We cannot turn back."

America, we cannot turn back. Not with so much work to be done. Not with so many children to educate, and so many veterans to care for. Not with an economy to fix and cities to rebuild and farms to save. Not with so many families to protect and so many lives to mend. America, we cannot turn back. We cannot walk alone. At this moment, in this election, we must pledge once more to march into the future. Let us keep that promise - that American promise - and in the words of Scripture hold firmly, without wavering, to the hope that we confess.
