Pseudo-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.
Otherwise; Having given them some commands for the sanctification of prayer, saying, Judge not, He adds accordingly, Ask, and it shall be given unto you, as though He were to say, If ye observe this mercy towards your enemies, whatever seems to you shut, knock, and it shall be opened to you. Ask therefore in prayer, praying day and night; seek with care and toil; for neither by toiling only in the Scriptures do we gain knowledge without God’s grace, nor do we attain to grace without study, lest the gift of God should be bestowed on the careless. But knock with prayer, and fasting, and alms. For as one who knocks at a door, not only cries out with his voice, but strikes with his hand, so he who does good works, knocks with his works. But you will say, this is what I pray that I may know and do, how then can I do it, before I receive? Do what you can that you may become able to do more, and keep what you know that you may come to know more. Or otherwise; having above commanded all men to love their enemies, and after enjoined that we should not under pretext of love give holy things to dogs; He here gives good counsel, that they should pray God for them, and it shall be granted them; let them seek out those that are lost in sins, and they shall find them; let them knock at those who are shut up in errors, and God shall open to them that their word may have access to their souls. Or otherwise; Since the precepts given above were beyond the reach of human virtue, He sends them to God to whose grace nothing is impossible, saying, Ask, and it shall be given you, that what cannot be performed by men may be fulfilled through the grace of God. For when God furnished the other animals with swift foot, or swift wing, with claws, teeth, or horns, He so made man that He Himself should be man’s only1 strength, that forced by reason of his own weakness, he might always have need of his Lord.
