Mark's Gospel reveals a very human side of Jesus. Jesus didn't interact with people, heal people, and cast out demons from a God-platform. The glory of all that it means to be God was hidden from us, and Jesus chose to pursue His humanity and be as frail as the rest of us.
A human saved the world.
He's someone you can identity with because He experienced your weaknesses. He's someone accessible because He became like you. And, He's a friend.
