These characteristics help us understand Mark's purpose for writing, which he did not state directly. Mark's purpose was not just to give his readers a biographical or historical account of Jesus' life. He had a more practical purpose. The biographical material he chose to include and omit suggests that he wanted to enable his Christian readers to endure suffering and persecution for their faith effectively. To do this he recorded much about Jesus' sufferings. About one third of this Gospel deals with the passion of Jesus. Moreover there are many other references to suffering throughout the book (e.g., 1:12-13; 3:21-22, 30-35; 8:34-38; 10:30, 33-34, 45; 13:8, 11-13). Clearly Mark implied that faithfulness and obedience as a disciple of Jesus will inevitably result in opposition, suffering, and perhaps death. This emphasis would have ministered to the original readers who were undergoing persecution for their faith. It is a perennial need in pastoral ministry.11
Mark had a theological as well as a pastoral purpose in writing. It was to stress the true humanity of the Son of God. Whereas Matthew presented Jesus as the Messiah, Mark showed that He was the human servant of God who suffered as no other person has suffered. Mark stressed Jesus' obedience to His Father's will. This emphasis makes Jesus an example for all disciples to follow (10:45). One wonders if Mark presented Jesus as he did to balance a tendency that existed in the early church to think of Jesus as divine but not fully human.
