“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.”
