I've really been struck by how closely Heidelberg Catechism, Question 2 mirrors the book of Exodus.
Exodus shows misery of our sin and slavery, the drama of our freedom--purchased by God by the blood of the lamb-- and then leads us to His 10 words/commandments---as a path for us to know how to live the free life in gratitude for such redemption.
What must you know to live and die in the joy of this comfort?
Answer. Three things: first, how great my sin and misery are; second, how I am set free from all my sins and misery; third, how I am to thank God for such redemption.
