“I'm still so remote from God that I don't even sense his presence when I pray.”
As quoted in At the Heart of the White Rose: Letters and Diaries of Hans and Sophie Scholl (1987) edited by Inge Jens, translated by J. Maxwell Brownjohn; also in Voices of the Holocaust : Resistors, Liberation, Understanding (1997) by Lorie Jenkins McElroy
Context: I'm still so remote from God that I don't even sense his presence when I pray. Sometimes when I utter God's name, in fact, I feel like sinking into a void. It isn't a frightening or dizzying sensation, it's nothing at all — and that's far more terrible. But prayer is the only remedy for it, and however many devils scurry around inside me, I shall cling to the rope God has thrown me in Jesus Christ, even if my numb hands can no longer feel it.

“Pray for rain all you like, but dig a well as you do it.”
