Ambrose of Milan
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.
Who is a greater friend to us, than He who delivered up His body for us? Now we have here another kind of command given us, that at all times, not only in the day, but at night, prayers should be offered up. For it follows, And shall go into him at midnight. (Ps. 119:62.) As David did when he said, At midnight I will rise and give thanks unto thee. For he had no fear of awakening them from sleep, whom he knew to be ever watching. For if David who was occupied also in the necessary affairs of a kingdom was so holy, that seven times in the day he gave praise to God, (Ps. 119:164.) what ought we to do, who ought so much the more to pray, as we more frequently sin, through the weakness of our mind and body? But if thou lovest the Lord thy God, thou wilt be able to gain favour, not only for thyself, but others. For it follows, And say unto him, Friend, lend me three loaves, &c.
