“This is our moment. This is our time, to put our people back to work and open doors of opportunity for our kids; to restore prosperity and promote the cause of peace; to reclaim the American Dream and reaffirm that fundamental truth, that, out of many, we are one; that while we breathe, we hope. And where we are met with cynicism and doubts and those who tell us that we can't, we will respond with that timeless creed that sums up the spirit of a people: Yes, we can.
Thank you. God bless you. And may God bless the United States of America.”

2010s, Farewell Speech (2017)
Context: When you encounter obstacles — because I guarantee you, you will, and many of you already have — when you are struggling and you start thinking about giving up, I want you to remember something that my husband and I have talked about since we first started this journey nearly a decade ago, something that has carried us through every moment in this White House and every moment of our lives, and that is the power of hope — the belief that something better is always possible if you're willing to work for it and fight for it.
It is our fundamental belief in the power of hope that has allowed us to rise above the voices of doubt and division, of anger and fear that we have faced in our own lives and in the life of this country. Our hope that if we work hard enough and believe in ourselves, then we can be whatever we dream, regardless of the limitations that others may place on us. The hope that when people see us for who we truly are, maybe, just maybe they, too, will be inspired to rise to their best possible selves.

2017, Farewell Address (January 2017)

2011, Remarks on death of Osama bin Laden (May 2011)
Context: On September 11, 2001, in our time of grief, the American people came together. We offered our neighbors a hand, and we offered the wounded our blood. We reaffirmed our ties to each other, and our love of community and country. On that day, no matter where we came from, what God we prayed to, or what race or ethnicity we were, we were united as one American family.
We were also united in our resolve to protect our nation and to bring those who committed this vicious attack to justice. We quickly learned that the 9/11 attacks were carried out by al Qaeda — an organization headed by Osama bin Laden, which had openly declared war on the United States and was committed to killing innocents in our country and around the globe. And so we went to war against al Qaeda to protect our citizens, our friends, and our allies.

2010s, Farewell Speech (2017)
Context: If your family doesn't have much money, I want you to remember that in this country, plenty of folks, including me and my husband — we started out with very little. But with a lot of hard work and a good education, anything is possible — even becoming President. That's what the American Dream is all about.
If you are a person of faith, know that religious diversity is a great American tradition, too. In fact, that's why people first came to this country — to worship freely. And whether you are Muslim, Christian, Jewish, Hindu, Sikh — these religions are teaching our young people about justice, and compassion, and honesty. So I want our young people to continue to learn and practice those values with pride. You see, our glorious diversity — our diversities of faiths and colors and creeds — that is not a threat to who we are, it makes us who we are.
