John Chrysostom
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.
And in that He adds seek, and knock, He bids us ask with much importunateness and strength. For one who seeks, casts forth all other things from his mind, and is turned to that thing singly which he seeks; and he that knocks comes with vehemence and warm soul.
