In chapter IV of the book, Strength of love, Martin Luther has discussed the behavior of humans and the reason of their cruel conducts. King has mentioned few events in entirely different aspect which reveals that human badness is actually nothing but their blindness towards right.
The Jesus prayer on the cross was filled of wise and rational lessons for those who can understand. Jesus said: “They not know what they do” (Jesus, pg. 40). This shows Jesus awareness about human’s insight, intellectual level and their spiritual blindness. He knows that the people are unaware of the sin they are doing by hurting Jesus as it was not their evilness but their blindness and unconsciousness.
History contains another event of human blindness, the death of Socrates. Socrates was compelled to drink poison by the citizens of Greece. The Greeks were the respectable and genuine people who thought Socrates is an atheist and his thoughts and preaching could harm the society. In actual, his beliefs were deep and out of traditions which seemed new to the people and out of illiteracy they killed Socrates. This is an example which depicts that humans need enlightenment and spiritual awareness so that they can avoid sins and troubles.
Similarly, the slavery in America had the same reason. The white doctrine came into existence and people assume that this regime is beneficial for all and start flowing it instinctively. Gradually, Negro was considered biologically inferior and born slaves. This created a class difference on large scale and became a trend in America. According to one frame work:
“All men are made in the image of God;
God, as everyone know, is not a Negro;
Therefore, Negro is not a man.” (King. Pg. 42)
This example depicts that whatever sins have been done in past and are still ongoing are due to lack of understanding and by following the dictators blindly. Human has been gifted with intellectual brain which should be utilized to avoid any injustice.
