Rescue

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."
