What is the subject of the passage
"all great and honourable actions are accompanied with great difficulties, and must be both enterprised and overcome with answerable courages. it was granted ye dangers were great, but not desperate; the difficulties were many, but not invincible. for though their were many of them likely, yet they were not certaine; it might be sundrie of ye things feared might never befale; others by providente care and ye use of good means, might in a great measure be prevented; and all of them, through ye of god, by fortitude and patience, might either be borne, or overcome."
