A few years ago, a subway stop in New York City had two movie posters right next to each other. The first poster was for the film Extraordinary Measures, starring Brendan Fraser and Harrison Ford. The tagline for the film was "Don't Hope for a Miracle: Make One." The second poster, for the film The Book of Eli starring Denzel Washington, had this tagline: "Deliver Us."

Both films represent two radically different approaches to life. Extraordinary Measures summarizes life under the law. The basic message is this: You are on your own, so your salvation, however you define that word, is up to you. The basic message of The Book of Eli summarizes the gospel: You are not on your own, so your salvation is a gift from the true deliverer. When we cry for deliverance, he will answer us.
