Why is the Gospel of Mark said to present Jesus as "the Servant"? It is often asserted that the Gospel of Mark distinctively presents Jesus as the Servant, even the Suffering Servant of Isaiah 53.

What is it about the particular content of the gospel of Mark that gives rise to this assertion?  What is the basis for this distinction?
Since Mark presents the Savior as a Slave, he does not tell His genealogy and status, as the ancestry of a slave is not worthy of note. Mark also does not intend to impress us with the Slave’s wonderful words (as Matthew does with His marvelous teachings and parables concerning the heavenly kingdom, and John with His profound revelations of divine truths), but he impresses us with His excellent deeds in His gospel service, providing more detail than the other Gospels, in order to portray the Slave-Savior’s diligence, faithfulness, and other virtues in the saving service He rendered to sinners for God. 

In Mark’s Gospel is the fulfillment of the prophecy concerning Christ as the Slave of Jehovah in Isaiah 42:1-4, 6-7; 49:5-7; 50:4-7; 52:13—53:12, and the details of the teaching regarding Christ as the Slave of God in Philippians 2:5-11. His diligence in labor, His need of food and rest (Mark 3:20-21; 6:31), His anger (3:5), His groaning (7:34), and His affection (10:21) display beautifully His humanity in its virtue and perfection. His lordship (2:28), His omniscience (2:8), His miraculous power, and His authority to cast out demons (1:27; 3:15), to forgive sins (2:7, 10), and to silence the wind and the sea (4:39) manifest in full His deity in its glory and honor. Such a Slave served sinners as their Slave-Savior, with His life as their ransom (10:45), for the fulfillment of the eternal purpose of God, whose Slave He was.
