Book excerpt: "This timeless little classic communicates essential teachings of Martin Luther. Luther's great insight into the freedom of the Christian proved revolutionary in his century and remains timely and poignantly relevant in our own. For the Christian, this freedom means liberty from sin and death, as well as the opportunity to serve one's neighbor. Written in a simple style, On Christian Liberty conveys profound spiritual discernment about the grace of God and liberating faith in Christ Jesus. This translation, down-to-earth and accessible, brings one of the great Reformer's most important works to a new generation of readers." --from the publisher.
