Cover art for Hope Is... lyrics by Killswitch Engage

In my opinion, I don't think it's about rebellion, but rather, "fighting the good fight" or "running the good race." Being a believer. He's saying do not despair because there is so much sin in the world because "hope is not lost." "Let the strength of your words be the spark that ignites the flame" - Preach the gospel and allow your word to spread the gospel through the people like a fire. "Proclaim your freedom, give voice to your liberation" - Tell people how Jesus set you free and has liberated you from the ways of the world and sin." "weep no more/grieve no more, we will prevail" He's saying fear not, because we've already won. As spoken in revalation, Satan and the world has already been defeated, so there's no reason to to be saddened. "revoke the needless way of affliction, revoke and abandon" - rebuke sin in your life and try to live your life as holy as possible so to be a witness unto the nations. "we are the authors, finishers of our faith" - that's scripture straight from the bible. "we are the solution" - how we are the only ones who can spread the word and bring people to Jesus Christ before the rapture. Awesome song... they are really amazing, can't wait to see them in concert with In Flames and As I Lay Dying this Thursday.
