One of the primary themes in the book of Mark is his focus on Jesus as a suffering servant. Maybe the most famous verse in this Bible book is Mark 10:45 where Jesus says, “For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many.” Jesus makes it very clear that he came to suffer, serve us, and give his life as a ransom for all who will turn from their sin and believe in him.
