Donald MacLeod argues that our understanding of the Trinity matters because 'it is the model for the way we should live, particularly in our relations with one another.' The relationship between Father, Son and Spirit is laid out in Scripture, and although fully grasping the concept of this divine mystery will always be beyond us, we can understand it better. It is critically important that we do, for if our understanding of God is wrong, it may lead to other wrong beliefs.

Donald MacLeod's faithful insight into what Scripture has to say about the Godhead is priceless, as relevant now as when it was first published. This 30th anniversary edition will be an invaluable resource to a new generation of readers.
