Solara: You know, you say you've been walking for thirty years, right? Eli: Right? Solara: Have you ever thought that maybe you were lost? Eli: Nope. Solara: Well, how do you know that you're walking in the right direction? Eli: I walk by faith, not by sight. Solara: [sighs] What does that mean? Eli: It means that you know something even if you don't know something. Solara: That doesn't make any sense. Eli: It doesn't have to make sense. It's faith, it's faith. It's the flower of light in the field of darkness that's giving me the strength to carry on. You understand? Solara: Is that from your book? Eli: No, it's, uh, Johnny Cash, Live at Folsom Prison.
