What can we learn we can use in our walk with Christ from this man who devoted his life to seeking justice for those who weren't receiving it. He literally changed the face of the South and helped the United States to better live out it's ideals that all men are created equal for example.
He showed us how to walk in love without retaliating - how to "turn the other cheek" and how to serve!
Ultimately he gave his life for the cause eschewing wealth to help the "least of these."
