Augustine of Hippo
Catena Aurea · Matthäusevangelium 7
Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.
(Serm. in Mont. ii. 21.) Asking, is that we may get healthiness of soul that we may be able to fulfil the things commanded us; seeking, pertains to the discovery of the truth. But when any has found the true way, he will then come into actual possession, which however is only opened to him that knocks.
