The Saviors of God (1923)
Context: God is imperiled. He is not almighty, that we may cross our hands, waiting for certain victory. He is not all-holy, that we may wait trustingly for him to pity and to save us.
Within the province of our ephemeral flesh all of God is imperiled. He cannot be saved unless we save him with our own struggles; nor can we be saved unless he is saved.
We are one. From the blind worm in the depths of the ocean to the endless arena of the Galaxy, only one person struggles and is imperiled: You. And within your small and earthen breast only one thing struggles and is imperiled: the Universe.

Light (1919), Ch. VII - A Summary
Context: I am looking for the happiness which lives. And truly, when I have a sense of some new assent wavering and making ready, or when I am on the way to a first rendezvous, I feel myself gloriously uplifted, and equal to everything!
This fills my life. Desire wears the brain as much as thought wears it. All my being is agog for chances to shine and to be shared. When they say in my presence of some young woman that, "she is not happy," a thrill of joy tears through me.
