Pete Enns in his Introduction to his Exodus commentary writes:
The book of Exodus is not waiting there for us to bring it into our world. Rather, it is standing there defining what our world should look like and then inviting us to enter that world.
He explains a bit more of what he means by this:
The story of Exodus... is designed to tell us what God is like, how he thinks of his people, the lengths to which he will go to deliver them, and the proper response of God's people to this great deed. Applying the book of Exodus begins with understanding what the story is supposed to do and then seeing how we, as God's people, fit into that story.
"You will always give effortlessly to that which is your salvation, to those things that give your life meaning. If Jesus is the One who saved you, your money flows out easily into His work, His people, His causes. If, however, your real religion is your appearance, your social status, or your pleasure, your money flows most easily into those items and symbols. Radical generosity is therefore an inevitable sign of real grace in the heart."
