Keeping Christ's Commandments: A True Manifestation of Love to Him, by John Brown of Edinburgh, shows how true love for God is demonstrated by obedience to his revealed will, which is summarized in the Ten Commandments.

Gnostic and Anabaptist tendencies (seen primarily in Charismatic circles), which rely on extra-biblical sources of guidance (such as mystic impressions, emotions, tongues, and so-called "prophecies"), all ultimately deny sola Scriptura and undermine the Reformation. This work is based on the words of our Lord, "If ye love me, keep my commandments."
