What does the metaphor cashing a check mean

A metaphor is a figure of speech that directly refers to one thing while mentioning another one. Metaphors are meant to establish clarity between ideas, or a link that connects them.

In this case, Martin Luther King Jr. presents the metaphor of "cashing a check" in order to refer to the Civil Rights Movement. His argument is that the United States had given black people a "check," which refers to their rights. However, these had not been realized. Therefore, in "cashing" this check, black people were asking to receive what the country had promised them before: equal rights.

to kill a mockingbird basically is about a lawyer who goes against everything in a racist society like at the time of this novel, to defend a black man accused of sexual abuse. in the bible there are cases like that of joseph, who was accused by the woman of potifar, for a crime similar to that of tim robbinson, of that novel (genesis 39: 1-20). at this point we see that god also provides the escape to joseph, who was accused unjustly, but in his time, and through his attitude, his faith was not shaken, and god provided the solution. the perspective of god also written in the bible and not pay evil with evil. (ephesians 4: 32, 1 thessalonians 5: 15, 1 peter 3: 9). atticus, the lawyer, demonstrated during this lee novel, empathy, love of neighbor, understood the situation of this accused man. he went against everything in that society, and stood in favor of that man, for the injustice committed. this shows the empathy, the love taught by christ, in some passages that speak of love and justice in the sermon of the beatitudes (especially verses 6 and 7 of matthew 5).
