Basil the Great
Catena Aurea · Lukasevangelium 11
And he said unto them, Which of you shall have a friend, and shall go unto him at midnight, and say unto him, Friend, lend me three loaves; For a friend of mine in his journey is come to me, and I have nothing to set before him? And he from within shall answer and say, Trouble me not: the door is now shut, and my children are with me in bed; I cannot rise and give thee. I say unto you, Though he will not rise and give him, because he is his friend, yet because of his importunity he will rise and give him as many as he needeth.
(Const. Mon. c. 1.) For perhaps He delays purposely, to redouble your earnestness and coming to him, and that you may know what the gift of God is, and may anxiously guard what is given. For whatever a man acquires with much pains he strives to keep safe, lest with the loss of that he should lose his labour likewise.
