Today, nearly half a century after Martin Luther King, Jr. led the historic March on Washington for equality, tens of thousands came to the National Mall in Washington, D.C. for the Martin Luther King, Jr. Memorial Dedication. The memorial to Dr. King has been open since August, but the dedication was delayed due to Hurricane Irene. As President Obama said, though delayed, "this is a day that would not be denied."

President Obama, joined by the First Family, toured the memorial and then spoke at the dedication ceremony in honor of Dr. King's work to make his dream a reality for all. During his speech, President Obama reminded us that the progress towards Dr. King's vision has not come easily and there is still more to do to expand opportunity and make our nation more just:

Our work is not done.  And so on this day, in which we celebrate a man and a movement that did so much for this country, let us draw strength from those earlier struggles.  First and foremost, let us remember that change has never been quick.  Change has never been simple, or without controversy.  Change depends on persistence.  Change requires determination.  It took a full decade before the moral guidance of Brown v. Board of Education was translated into the enforcement measures of the Civil Rights Act and the Voting Rights Act, but those 10 long years did not lead Dr. King to give up.  He kept on pushing, he kept on speaking, he kept on marching until change finally came. 

And then when, even after the Civil Rights Act and the Voting Rights Act passed, African Americans still found themselves trapped in pockets of poverty across the country, Dr. King didn’t say those laws were a failure; he didn’t say this is too hard; he didn’t say, let’s settle for what we got and go home.  Instead he said, let’s take those victories and broaden our mission to achieve not just civil and political equality but also economic justice; let’s fight for a living wage and better schools and jobs for all who are willing to work.  In other words, when met with hardship, when confronting disappointment, Dr. King refused to accept what he called the “isness” of today.  He kept pushing towards the “oughtness” of tomorrow.

And so, as we think about all the work that we must do –- rebuilding an economy that can compete on a global stage, and fixing our schools so that every child -- not just some, but every child -- gets a world-class education, and making sure that our health care system is affordable and accessible to all, and that our economic system is one in which everybody gets a fair shake and everybody does their fair share, let us not be trapped by what is.  We can’t be discouraged by what is.  We’ve got to keep pushing for what ought to be, the America we ought to leave to our children, mindful that the hardships we face are nothing compared to those Dr. King and his fellow marchers faced 50 years ago, and that if we maintain our faith, in ourselves and in the possibilities of this nation, there is no challenge we cannot surmount.

The President addressed some of the issues that continue to challenge our country and how Dr. King's "constant insistence on the oneness of man" encourages us to see through each other's eyes as we face disagreement:

If he were alive today, I believe he would remind us that the unemployed worker can rightly challenge the excesses of Wall Street without demonizing all who work there; that the businessman can enter tough negotiations with his company’s union without vilifying the right to collectively bargain.  He would want us to know we can argue fiercely about the proper size and role of government without questioning each other’s love for this country -- with the knowledge that in this democracy, government is no distant object but is rather an expression of our common commitments to one another.  He would call on us to assume the best in each other rather than the worst, and challenge one another in ways that ultimately heal rather than wound.

Looking towards the future, President Obama spoke to the inspiration Dr. King instills in us to this day to continue his legacy:

He would not give up, no matter how long it took, because in the smallest hamlets and the darkest slums, he had witnessed the highest reaches of the human spirit; because in those moments when the struggle seemed most hopeless, he had seen men and women and children conquer their fear; because he had seen hills and mountains made low and rough places made plain, and the crooked places made straight and God make a way out of no way.

And that is why we honor this man –- because he had faith in us.  And that is why he belongs on this Mall -– because he saw what we might become.  That is why Dr. King was so quintessentially American -- because for all the hardships we’ve endured, for all our sometimes tragic history, ours is a story of optimism and achievement and constant striving that is unique upon this Earth.  And that is why the rest of the world still looks to us to lead.  This is a country where ordinary people find in their hearts the courage to do extraordinary things; the courage to stand up in the face of the fiercest resistance and despair and say this is wrong, and this is right; we will not settle for what the cynics tell us we have to accept and we will reach again and again, no matter the odds, for what we know is possible.

That is the conviction we must carry now in our hearts.  As tough as times may be, I know we will overcome.  I know there are better days ahead.  I know this because of the man towering over us.  I know this because all he and his generation endured -- we are here today in a country that dedicated a monument to that legacy. 

And so with our eyes on the horizon and our faith squarely placed in one another, let us keep striving; let us keep struggling; let us keep climbing toward that promised land of a nation and a world that is more fair, and more just, and more equal for every single child of God.
