Jack is here because he has to do something. He can't be told what that is. He's gotta find it himself. Sometimes you can just hop in the back of someone's cab and tell them what they're supposed to do. Other times you have to let him look out at the ocean for awhile.
--Jacob to Hurley (in whose cab Jacob did hop once upon a time) at the end of The Lighthouse episode of Lost
As I watched this scene, I couldn't help but reflect that the contrast between how Hurley and Jack communicate with Jacob (who appears to be something other than human with powers beyond human capability) bears some resemblence to how we humans experience our relationship with God. Sometimes it feels like God speaks simply and clearly--be it through his Word, other people, his Spirit within us or our prayers. Sometimes, God seems silent. And sometimes, like Jack, it takes us awhile to get ourselves into a place where we can hear his voice and direction.
