What does Martin Luther King predict will happen if justice is denied African Americans?

Martin Luther King predicted that if justice is denied to African Americans that there will be revolts happening around. He mentioned that the oppressed would not remain oppressed forever. If a person yearns for freedom, in one form or another it will eventually be manifested. He even told about the Bible story of Moses and how he stood against the Pharaoh just to let his people go. It will continue as per him. There would be endless turbulent struggles that will happen due to racial injustice.
