Cover art for Let The Sparks Fly lyrics by Thousand Foot Krutch

In the song he is pleading to a friend, or someone he cares about to come to know Christ, and receive the Holy Spirit. "Let me take you into the light, there's nowhere to hide, there's nothing but darkness left here." The light is Jesus (called that many times in the Bible) and he wants to pull them out of the darkness (the world) and into relationship with Jesus. "Heaven's not far away, and I'm not gonna leave you here." Death is not that far away from any of us. It can happen at any moment, so there can't be any hesitation when it comes to accepting Jesus. That's why he says "there's no such thing as maybe... no more hesitating. Let the sparks fly..." He's saying to stop hesitating and just become on fire for Jesus.
