expression
knock, and it shall be opened unto you; God answers prayers
A biblical proverb from Matthew 7:7, used to express that sincere effort or prayer will be rewarded. Often cited in religious or moral contexts.
「叩けよさらば開かれん」という聖書の言葉を信じて、彼は毎日祈り続けた。
Believing in the biblical phrase 'knock, and it shall be opened unto you,' he continued to pray every day.
From the Japanese translation of Matthew 7:7 in the Bible. The phrase uses classical imperative 叩けよ (knock) and the archaic conjunction さらば (then), followed by the classical passive 開かれん (shall be opened).
