Here’s the critical part of Obama’s speech 

We are living in a time when it can be hard to hope. Each day we wake up to some new assault on our democratic institutions, another setback to the idea of the rule of law. An offense to common decency. Every day you wake up to it, to things you just didn’t think were possible. Each day, we’re told by those in high office to fear each other and to turn on each other — and that some Americans count more than others, and that some don’t even count at all. Everywhere we see greed and bigotry being celebrated, and bullying and mockery masquerading as strength; we see science and expertise denigrated while ignorance and dishonesty, and cruelty and corruption, are reaping untold rewards. Every single day we see that. And it’s hard to hope in those moments.

So it may be tempting to get discouraged, to give in to cynicism. It may be tempting for some to compromise with power and grab what you can, or even for good people, to maybe just put your head down and wait for the storm to pass.

But this man — Reverend Jesse Louis Jackson — inspires us to take the harder path. His voice calls on each of us to be heralds of change, to be messengers of hope; to step forward and say “Send me” wherever we have a chance to make an impact — whether it’s in our schools, in our workplaces, in our neighborhoods and our cities. Not for fame, not for glory, or because success is guaranteed, but because it gives our life purpose, because it aligns with what our faith tells us God demands, and because if we don’t step up, no one else will.
