Amazon.com description: Product Description: This book is not to be judged by its size. It is crammed full of good things. It is like a bugle call to battle, but it is more. In arresting and picturesque language, it sets forth the reasons why people should bestir themselves for the honor of the King of kings. Dr. Zwemer has covered a vast amount of ground, and has laid under tribute a multitude of facts which illustrate the hopefulness of the task which engages the attention of the Christian Church and deepens the conviction that the Christ of God shall yet wear the crown of universal dominion.
