Who said “In our era, the road to holiness necessarily passes through the world of action.”?

“Let us be tried by our actions.”

“As you make your bed, so you must lie in it.”

“To strive, to seek, to find, and not to yield.”

“I never "worry" about action, but only about inaction.”

“We are always getting ready to live, but never living.”

“Time goes by, reputation increases, ability declines.”

“We are not permitted to choose the frame of our destiny. But what we put into it is ours.”

“Life only demands from you the strength you possess. Only one feat is possible — not to have run away.”

“Your cravings as a human animal do not become a prayer just because it is God whom you ask to attend to them.”

“In the last analysis it is our conception of death which decides our answers to all the questions life puts to us.”

“What makes loneliness an anguish is not that I have no one to share my burden, but this: I have only my own burden to bear.”
