• Vocalist Justine Jones explained the song's meaning to Kerrang:
  
  "Everyone in life should have a passion, be it big or small. Something that fills them with purpose and happiness. The Warmth of a Dying Sun is about trying to achieve those goals and life, even though they seem unachievable. There will always be naysayers, and people that think they have life figured out, but it's important you do what you want with your life and not from a pre-set path."
• The song is not only a plea to follow one's passion, but also serves as a lyrical ode to the band itself. "I see the warmth as a metaphor for being on-stage and feeling like this is where I belong, where I've always wanted to be since I was a kid," Jones explained to The Independent, "and the dying sun represents self-doubt, the voice in the back of your head that reminds you that one day you're going to be too old to do this or one day you're going to have to give this up to start a family or pay your bills ... things like that."
  
  "Essentially, I think everyone should have a passion for something the fills them with a sense of purpose," she continued, "and the song is about the relentless pursuit of that passion."
