[1] what we are directly TOLD about a character
[2] what we are SHOWN about a character — what he or she says and does — how other characters respond to or say about them.
Mark primarily shows what his characters are like through action and dialogue. There is virtually no description of physical appearances. Rather, Mark values his characters primarily as human agents in the drama of life. And he is particularly aware of their place in society as descriptive and determinative of who they are.
Characters as individuals in ancient Greco-Roman literature tended to be stylized, unchanging and predictable. Within this context, Mark shows Jesus to be highly individual and complex. We see in his life someone who is fully engaged and transformed through his obedience and submission to God.
