G. Campbell Morgan emphasizes that the Church of the living God must reveal the Person of Christ to be meaningful and effective. He argues that without Christ, the Church is merely an empty structure, lacking purpose and value. The Church serves as the instrument through which Jesus shows Himself to the world, and if it fails to proclaim His Word, it becomes a mere noise without substance. Morgan highlights the necessity of the Church in making the light of Christ visible and accessible to humanity, asserting that the true essence of the Church lies in its ability to reflect and communicate the teachings of Jesus.
