A theological study and brief introduction to the Gospel of Mark. In this book, the author emphasizes that the Gospel of Mark is not merely intended as a historical account of Jesus' life, but as a theological portrait that presents Jesus' identity as the Messiah and Son of God through His suffering, ministry, death, and resurrection. The author invites readers to understand the structure and main themes of the Gospel of Mark, such as the messianic secret, the meaning of discipleship, faith, suffering, and the relationship between power and the cross. He also shows how Mark constructs Jesus' story dramatically to challenge his readers to understand what it means to follow Christ. With language that is accessible yet academic, this book is an important introduction for theology students and general readers who want to deepen the theological message of the Gospel of Mark.
