Songfacts®:

• Look Up Child contains several tracks on which Lauren Daigle offers support to other believers; there are songs about comfort ("Your Wings"), and contentment ("Everything"). "Rescue" is a song about reassurance and hope sung from the perspective of God.
  
  I will send out an army to find you
  In the middle of the darkest night
  It's true, I will rescue you
  
  Daigle told Billboard that "Rescue" is the most personal song on the album, explaining, "It was written for someone very close to me who was going through a difficult time. I wanted something that would comfort them in their time of need. That's the purpose of the song, to give hope to people who feel lost...the landscape is synonymous to the depth of healing that can take place where you feel void or empty. When hope arrives in such an expansive way it can rescue you."
• The song was featured on the seventh episode of Grey's Anatomy's 15th season, which premiered on November 8, 2018.
• The music video was directed by John Gray and was filmed over two days on the Knik Glacier in Alaska. Gray explained that the visual remoteness was intended to symbolize "a simplicity and beauty that transforms as the song progresses."
• Lauren Daigle also released a Spanish-language version of the song titled "Rescate" for her Latin American fans.
• Lauren Daigle wrote "Rescue" with a specific loved one in mind. It stands out as a rare instance for the singer where the emotional intent was clear from the very first spark of the idea.
  
  Daigle began writing the song with a vivid mental image of a young woman trapped in desperation, cycling through different vices in search of even the smallest sense of hope. In this vision, Jesus appears, not as a judge or fixer, but as a quiet presence who sits with her in the middle of her pain. Rather than condemning her choices or trying to repair her life, He simply stays, offering companionship in the darkest moment.
  
  That image gave Daigle part of the chorus, which she brought into the studio unsure of herself but deeply attached to the idea. She recalled feeling unusually connected to the song as a writer, sensing that it was "real" in a way her earlier work hadn't always been. The writing session with producers Paul Mabury and Jason Ingram moved quickly, and the song came together in about an hour and 15 minutes.
• After recording a demo vocal, Maybury and Ingram encouraged Daigle to sing the song while thinking directly about the person who inspired it. That shift changed the tone. She focused on how she would want the song to sound if she were singing it straight to that loved one, and, by extension, to anyone who feels hopeless, desperate, or at the end of their rope.
