The very concept of 'truth' has been questioned in recent times. Is the notion of 'your truth' valid, or is there such a thing as the truth—an ultimate truth that is the same for every person in every place?Is it up to individuals to decide what is true for them, or is there a higher authority that defines truth? Are all religious or philosophical insights valid, or is there a final authority in matters of belief?

These are questions which Martyn Lloyd-Jones addresses under the theme of authority—the authority of Jesus Christ; the authority of the Scriptures; and the authority of the Holy Spirit.

First published in 1958, Authority remains a foundational biblical treatment of an enduringly important theme.
