“How can there be three Gods and yet only one God?” Have you ever groaned inwardly at a question like this? Many of us find the doctrine of the Trinity – that God is three persons sharing one nature – difficult to get our heads round, and frankly a bit embarrassing. What is more, we seem to get by without thinking about it too deeply. But in reality, the Trinity is at the heart of all that Christians believe. The nature of God as a Trinity gives shape to all Christian truth, and to the gospel that we believe and proclaim. And rather than be a source of embarrassment, properly understood, it should fill us with joy. This book aims to help you see how the Trinity is fantastically good news. Because the trinity means that God is not remote and uninvolved – quite the opposite. God sent His Son and His Spirit into our world to draw us into a wonderful relationship with Himself. This is the God who gives meaning and joy to our lives. And along the way we discover that the Trinity answers other big questions: How can we know God? What happened at the cross? What does it mean to be human? How can people live together with all their differences? What does mission look like in a fragmented world? Tim Chester will take us deeper into understanding the thrilling triune nature of God. In short accessible chapters he takes us through the Bible’s teaching on the Trinity; gives us an overview of the important arguments over the trinity that have taken place throughout Christian history; and lays out the practical implications for our Christian lives.
