Locke: I believe that I was being tested.
Jack: Tested?
Locke: Yeah, tested. I think... that's why you and I don't see eye-to-eye sometimes, Jack because you're a man of science.
Jack: Yeah, and what does that make you?
Locke: Me, well, I'm a man of faith. Do you really think all this... is an accident? That we, a group of strangers survived, many of us with just superficial injuries? Do you think we crashed on this place by coincidence, especially this place? We were brought here for a purpose, for a reason, all of us. Each one of us was brought here for a reason.
Jack: Brought here? And who brought us here, John?
Locke: The island. The island brought us here. This is no ordinary place, you've seen that, I know you have. But the island chose you, too, Jack. It's destiny.
Jack: Did you talk with Boone about destiny, John?
Locke: Boone was a sacrifice that the island demanded. What happened to him at that plane was a part of a chain of events that led us here that led us down a path, that led you and me to this day, to right now.
Jack: And where does that path end, John?
Locke: The path ends at the hatch. The hatch, Jack all of it. All of it happened so that we could open the hatch.
Jack: No, no, we're opening the hatch so that we can survive.
Locke: Survival is all relative, Jack.
Jack: I don't believe in destiny.
Locke: Yes, you do. You just don't know it yet.
