This book is a course to introduce students to Christianity. The general purpose of this course has been clarified in the introduction to the student textbook. The modern church has a tendency to ignore the study of biblical history. Such negligence will inevitably lead to the loss of power. The gospel is a record of what has happened, and uncertainty about the gospel is a fatal weakness. For teachers and students, the most fundamental thing is to understand the facts of the Bible in an orderly manner.
