If it's a story about a modern - day 'good shepherd', it could be a social worker, for example. In this case, the main characters would be the social worker (the 'good shepherd') and the people they are helping (the 'flock'). The story might also include colleagues, family members of those being helped, and other individuals who play a role in the social worker's journey of caregiving.
Perhaps there are also the sheep that the shepherd takes care of. They could be important characters in the sense that their well - being is the focus of the shepherd's actions. And if it's a story set in a community, there could be other villagers or people who interact with the shepherd and are affected by his or her actions.
The main character in this story is Jesus as the good shepherd. His role is central as he is the one who watches over, protects, and guides. The other characters are implicitly the sheep which symbolize the followers or the believers. Jesus' relationship with the sheep is what the story is mainly about, showing his love, care, and sacrifice for them.
I'm not entirely sure as I haven't read the 'Good Shepherd' novel specifically. However, generally in a novel, main characters are those who drive the plot forward. They could be a protagonist, perhaps a shepherd who is the central figure, and there might be other supporting characters like the people in the shepherd's village, or those he meets on his journey.
The main character is obviously the shepherd. The shepherd is the central figure who takes care of the flock. And then there are the sheep which are the ones being cared for.
There could be a group of people who are being shepherded. Maybe some lost souls that the good shepherd is trying to guide. They would likely have different personalities and backstories that add to the complexity of the story.
The main character is Jesus as the Good Shepherd. And the sheep which represent the people or believers are also important in the story.
The main character is the shepherd boy. And the villagers are also important characters in the story.
The main characters are the shepherds and the angel. The shepherds are the ones who receive the news, and the angel is the messenger who brings the news of Jesus' birth to the shepherds.
The main characters in the shepherd boy story are the shepherd boy himself and the villagers.
In the religious context, the good shepherd is often seen as Jesus. He is considered to be like the shepherd who takes care of his flock (the believers).
The main character in a good shepherd story is, of course, the shepherd. He is the central figure who is responsible for the well - being of the sheep.
