The Gospel is primarily about God. Part of the glory of the New Testament is that it explains the Gospel to us in terms of the glorious work of the three persons of the Trinity. Yet many can miss the rich Trinitarian backdrop of the New Testament because they are not looking for it. Knowing the Trinity shows that knowing God is knowing Him as Triune and that to know Him is to love Him. Each chapter leads readers to meditate on God's work and how they relate to Him in light of passages of Scripture that appeal to all three divine Persons. The study questions included in each chapter are designed to promote personal devotion or group discussion. This book aims to show that the Trinity is the foundation of all biblical doctrines, the lifeblood of the Church, and the heart of Christian experience.
