Beyoncé graced the stage in a skintight white sequined dress. With her hair pulled back and a face of light makeup. As she belted out the heartfelt lyrics "I wanna leave my footprints on the sands of time" and "The hearts I have touched, will be the proof that I leave/That I made a difference, and this world will see I was here" the screens projected images of humanitarians making a difference around the world. Firefighters, charity organizations, teachers, volunteers and other great contributors to the world were spotlighted in the powerful montage.

The song's author, Diane Warren, was also present during the performance. According to The Huffington Post, Warren first shared the song to Beyoncé's husband Jay-Z who immediately called her after hearing the profound lyrics. The inspired songstress recorded the songs just days after the call.

World Humanitarian Day honors the 22 humanitarian workers who lost their lives in a terrorist attack in Iraq on August 19, 2003. It also recognizes all other humanitarian workers who have lost their lives working for humanitarian causes.

"I'd like to ask everyone to make sure they're a part of August 19th," Beyoncé said. "It's such a beautiful, beautiful day, and I'd like to honor the 22 people who lost their lives. God bless you all. Thank you so much for having me."

"I told [Beyoncé]: It's great that we have her, because she can reach millions of people," Under-Secretary General and Emergency Relief Coordinator Valerie Amos said while speaking with Anderson Cooper. "I could spend the rest of my life doing what I do, and I wouldn't reach a 10th of that number," she continued.

"Is this what happens at the U.N. every Friday night?" Cooper jokingly asked. "Because, I've gotta tell you ... I wanna be here every Friday night if this goes on."

All of the song's proceeds will be donated to the cause. The World Humanitarian Day website  was created to allow people to connect and share the good deeds they've done in their communities as well as make donations. Beyoncé and her organization set out to reach 1 billion people by August 19 and they have surpassed their goal by far.

"We all see the headlines, and we think, 'What can I really do to help?'" Beyoncé said in a statement. "World Humanitarian Day is an opportunity for all of us to work together to make a difference. This is our time to leave our mark on the world and show that we were here and we care."
