My favorite Martin Luther King Jr quotes:
"Take the first step in faith. You don't have to see the whole staircase, just take the first step."
"Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that."
"Never succumb to the temptation of bitterness."
"Science investigates religion interprets. Science gives man knowledge which is power religion gives man wisdom which is control."
