“There is a really deep well inside me. And in it dwells God. Sometimes I am there, too. But more often stones and grit block the well, and God is buried beneath. Then He must be dug out again.”

The Saviors of God (1923)
Context: We must understand well that we do not proceed from a unity of God to the same unity of God again. We do not proceed from one chaos to another chaos, neither from one light to another light, nor from one darkness to another darkness. What would be the value of our life then? What would be the value of all life?
But we set out from an almighty chaos, from a thick abyss of light and darkness tangled. And we struggle — plants, animals, men, ideas — in this momentary passage of individual life, to put in order the Chaos within us, to cleanse the abyss, to work upon as much darkness as we can within our bodies and to transmute it into light.

As a White Stone... (1916)
Context: As a white stone in the well's cool deepness,
There lays in me one wonderful remembrance.
I am not able and don't want to miss this:
It is my torture and my utter gladness. I think, that he whose look will be directed
Into my eyes, at once will see it whole.

Context: One cannot be in my position, looked to by some for guidance, without being constantly reminded of the awesomeness of its responsibility. I live with one deep concern: Am I making the right decisions? Sometimes I am uncertain, and I must look to God for guidance. There was one morning I recall, when I was in the Birmingham jail, in solitary, with not even my lawyers permitted to visit, and I was in a nightmare of despair. The very future of our movement hung in the balance, depending upon capricious turns of events over which I could have no control there, incommunicado, in an utterly dark dungeon. This was about ten days after our Birmingham demonstrations began. Over 400 of our followers had gone to jail; some had been bailed out, but we had used up all of our money for bail, and about 300 remained in jail, and I felt personally responsible. It was then that President Kennedy telephoned my wife, Coretta. After that, my jail conditions were relaxed, and the following Sunday afternoon -- it was Easter Sunday -- two S. C. L. C. attorneys were permitted to visit me. The next day, word came to me from New York that Harry Belafonte had raised $50,000 that was available immediately for bail bonds, and if more was needed, he would raise that. I cannot express what I felt, but I knew at that moment that God's presence had never left me, that He had been with me there in solitary.
