Speaking with us in a 2012 interview, Third Day frontman Mac Powell
said the band adopted a different approach musically to this song. He explained: "When I presented the song to the guys, it was just me and an acoustic guitar. So sometimes the way that the songs end up are what I hear in my head and sometimes they're way different. The guys from the band really brought about a great musical idea and tone to the song. I never really expected much from that song, even though I loved it, I thought, okay, this is a very up tempo kind of rock song. It's got a great message, but I don't know if people will actually get to the message because of the music. It has very much surprised me through the years how so many people's lives have been encouraged by that message of hope in 'Tunnel.'"
