From MLK's Stride Toward Freedom: It was January 27, 1956 and Martin Luther King Jr. had just received a death-threat on the phone.
I was ready to give up. With my cup of coffee sitting untouched before me, I tried to think of a way to move out of the picture without appearing a coward. In this state of exhaustion, when my courage had all but gone, I decided to take my problem to God. With my head in my hands, I bowed over the kitchen table and prayed aloud.
The words I spoke to God that midnight are still vivid in my memory. "I am here taking a stand for what I believe is right. But now I am afraid. The people are looking to me for leadership, and if I stand before them without strength and courage, they too will falter. I am at the end of my powers. I have nothing left. I've come to the point where I can't face it alone."
At that moment, I experienced the presence of the Divine as I had never experienced God before. It seemed as though I could hear the quiet assurance of an inner voice saying: "Stand up for justice, stand up for truth; and God will be at your side forever." Almost at once my fears began to go. My uncertainty disappeared. I was ready to face anything.
