I look forward to hosting an Iftar dinner celebrating Ramadan here at the White House later this week, and wish you a blessed month. - Barack Obama

But there comes a point in the speech where I find my cadence. The crowd quiets rather than roars. It's the kind of moment I'd come to recognize in subsequent years, on certain magic nights. There's a physical feeling, a current of emotion that passes back and forth between you and the crowd, as if your lives and theirs are suddenly spliced together, like a movie reel, projecting backward and forward in time, and your voice creeps right up to the edge of cracking, because for an instant, you feel them deeply; you can see them whole. You've tapped into some collective spirit, a thing we all know and wish for - a sense of connection that overrides our differences and replaces them with a giant swell of possibility - and like all things that matter most, you know the moment is fleeting and that soon the spell will be broken.

Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law, for if we are truly created equal, then surely the love we commit to one another must be equal, as well.

To dismiss the magnitude of this progress -- to suggest, as some sometimes do, that little has changed -- that dishonors the courage and the sacrifice of those who paid the price to march in those years. Medgar Evers, James Chaney, Andrew Goodman, Michael Schwerner, Martin Luther King Jr. -- they did not die in vain. Their victory was great. But we would dishonor those heroes as well to suggest that the work of this nation is somehow complete. The arc of the moral universe may bend towards justice, but it doesn’t bend on its own. To secure the gains this country has made requires constant vigilance, not complacency. Whether by challenging those who erect new barriers to the vote, or ensuring that the scales of justice work equally for all, and the criminal justice system is not simply a pipeline from underfunded schools to overcrowded jails, it requires vigilance. And we'll suffer the occasional setback. But we will win these fights. This country has changed too much. People of goodwill, regardless of party, are too plentiful for those with ill will to change history’s currents.
