The Gospel of Mark introduces Jesus as a leader who suffers to save his people, leaving the reader to decide if Jesus is the promised Messiah.
The Gospel of Mark gives a thorough account of Jesus' life and ministry without making a clear statement about Jesus' identity, and this is intentional. Mark shows people, even Jesus' disciples, questioning who Jesus is. And the second half of the book provides strong evidence that Jesus is indeed the Messiah.
Many Jews hoped that the Messiah would overthrow the Romans and rule as king, but as we read this book, we see that Jesus came as a servant to bring God's Kingdom. Despite his divine power, he sacrificed his life to save people from slavery to sin. The book's abrupt ending challenges us to decide if we believe he is the Messiah.
