Step-by-step explanation:
This is a question about “Salvation” by Langston Hughes
In this text the author shows how he was taken by his aunt to the Church so that he could have an encounter with jesus and convert to Christianity. In this context, the author shows how the preacher started a sermon where he said that there were many loose sheep in the cold, but the good shepherd called them and when they answered his call, they were under his protection, but one of these sheep decided to stay in the cold and not answer the call of the good shepherd. This symbolizes that the sheep are the people and that the good shepherd is Christ. Those who answer his call are under his protection, but those who refuse the call are unprotected, in discomfort.
