A video was directed by Christopher Louie, director of the EDM movie XOXO and uploaded January 3, 2017. Louie stated the video was inspired by the images of Omran Daqneesh, the Syrian boy whose home was bombed at night. "Like everyone in the world I was heartbroken by that image, but I also saw a glimmer of hope,” Louie said in a press release -- “As dark as the subject matter is, the point of our 'Believer' video was to capture the resilience of youth and the hope displayed by communities coming together to save victims from the rubble.” 
The video has been tied to the Save the Children organization with a link to donate in the description box.
