While many of us struggle to understand it, the Trinity is one of the most important teachings of the Christian faith: it defines God's very essence and describes how he relates to us. And while it can be a difficult concept to get our heads around, it matters that believers understand how God explains his own triune nature in his Word.

James R. White offers a concise and understandable account of what the Trinity is and why it matters, working from the biblical texts rather than from the later vocabulary alone. Along the way he refutes the distortions of God presented by various cults, which makes the book doubly useful to anyone who has had a Jehovah's Witness at the door. Revised and updated.
