Origen Patristic
c. A.D. 184–253
“But some one may seek to know, how it comes that they who pray are not heard? To which we must answer, that whose sets about seeking in the right way, omitting none of those things which avail to the obtaining of our requests, shall really receive what he has prayed to be given him. But if a man turns away from the object of a right petition, and asks not as it becomes him, he does not ask. And therefore it is, that when he does not receive, as is here promised, there is no falsehood. For so also when a master says, “Whoever will come to me, he shall receive the gift of instruction;” we understand it to imply a person going in real earnest to a master, that he may zealously and diligently devote himself to his teaching. Hence too James says, Ye ask and receive not, because ye ask amiss, (James 4:3.) namely, for the sake of vain pleasures. But some one will say, Nay, when men ask to obtain divine knowledge, and to recover their virtue they do not obtain? To which we must answer, that they sought not to receive the good things for themselves, but that thereby they might reap praise.”

c. A.D. 296–373
“(Dial. 1. de Trin.) Now unless the Holy Spirit were of the substance of God, Who alone is good, He would by no means be called good, since our Lord refused to be called good, inasmuch as He was made man.”
379
A.D.
Basil of Caesarea Patristic
c. A.D. 330–379
“(in Const. c. 1.) If also any one from indolence surrenders himself to his desires, and betrays himself into the hands of his enemies, God neither assists him nor hears him, because by sin he has alienated himself from God. It becomes then a man to offer whatever belongs to him, but to cry to God to assist him. Now we must ask for the Divine assistance not slackly, nor with a mind wavering to and fro, because such a one will not only not obtain what it seeks, but will the rather provoke God to anger. For if a man standing before a prince has his eye fixed within and without, lest perchance he should be punished, how much more before God ought he to stand watchful and trembling? But if when awakened by sin you are unable to pray stedfastly to the utmost of your power, check yourself, that when you stand before God you may direct your mind to Him. And God pardons you, because not from indifference, but infirmity, you cannot appear in His presence as you ought. If then you thus command yourself, do not depart until you receive. For whenever you ask and receive not, it is because your request was improperly made, either without faith, or lightly, or for things which are not good for you, or because you left off praying. But some frequently make the objection, “Why pray we? Is God then ignorant of what we have need?” He knows undoubtedly, and gives us richly all temporal things even before we ask. But we must first desire good works, and the kingdom of heaven; and then having desired, ask in faith and patience, bringing into our prayers whatever is good for us, convicted of no offence by our own conscience.”

John Chrysostom Patristic
A.D. 347–407
“(Hom. 23. in Matt.) Now by asking, He means prayer, but by seeking, zeal and anxiety, as He adds, Seek, and ye shall find. For those things which are sought require great care. And this is particularly the case with God. For there are many things which block up our senses. As then we search for lost gold, so let us anxiously seek after God. He shews also, that though He does not forthwith open the gates, we must yet wait. Hence he adds, Knock, and it shall be opened unto you; for if you continue seeking, you shall surely receive. For this reason, and as the door shut makes you knock, therefore he did not at once consent that you might entreat.”

Augustine of Hippo Patristic
A.D. 354–430
“(ubi sup.) Having laid aside the metaphor, our Lord added an exhortation, and expressly urged us to ask, seek, and knock, until we receive what we are seeking. Hence he says, And I say unto you, Ask, and it shall be given you.”
“(Serm. 105.) But He would not so encourage us to ask were He not willing to give. Let human slothfulness blush, He is more willing to give than we to receive.”
“(Serm. 105.) What great things the world speaks to thee, and roars them behind thy back to make thee look behind! O unclean world, why clamourest thou! Why attempt to turn him away! Thou wouldest detain him when thou art perishing, what wouldest thou if thou wert abiding for ever? Whom wouldest thou not deceive with sweetness, when bitter thou canst infuse false food?”

“(Serm. 105.) Therefore, O covetous man, what seekest thou? or if thou seekest any thing else, what will suffice thee to whom the Lord is not sufficient?”

“The words, I say unto you, have the force of an oath. For God doth not lie, but whenever He makes known any thing to His hearers with an oath, he manifests the inexcusable littleness of our faith.”

“For every one that asketh receiveth,.... Some indeed ask and receive not, because they ask amiss, Jam 4:3 who either apply to a wrong person, or ask in a wrong manner, or from wrong principles, or with wrong ends in view: but when a man is right in the object of prayer, and in the matter and manner of prayer, and in the end he proposes to himself, let him be what he will, of whatsoever nation, or ever mean a person, he has the petitions which he asks, either immediately, or, at least, he may be assured he shall have them in God's due time: and he that seeketh findeth; whoever not only prays, but makes use of means, as attendance on other ordinances, and is diligent in the use of them, sooner or later finds his account herein, and what his soul seeks for: and to him that knocketh it shall be opened; not only who prays heartily, and seeks diligently, but who is importunate, and will have no denial; continues knocking; though there may be some time a seeming delay, yet the door will not always be shut to him; after much knocking it will be opened; See Gill on Mat 7:8”

“And (or, therefore) I say unto you, Ask - Be importunate with God, not so much to prevail on him to save you, as to get yourselves brought into a proper disposition to receive that mercy which he is ever disposed to give. He who is not importunate for the salvation of his soul does not feel the need of being saved; and were God to communicate his mercy to such they could not be expected to be grateful for it, as favors are only prized and esteemed in proportion to the sense men have of their necessity and importance. See this subject explained Mat 7:7, Mat 7:8 (note).”

“Our petitions are frequently not immediately granted, that our earnestness and assiduity may be increased; that we may learn to esteem the gifts of God, and preserve them with care, for whatever we procure with labour, we preserve with care, lest by losing it we lose our labour also. (St. Basil in Con. Mon.)”

“(Severus Antioch.) Or by the word knock perhaps he means seeking effectually, for one knocks with the hand, but the hand is the sign of a good work. Or these three may be distinguished in another way. For it is the beginning of virtue to ask to know the way of truth. But the second step is to seek how we must go by that way. The third step is when a man has reached the virtue to knock at the door, that he may enter upon the wide field of knowledge. All these things a man acquires by prayer. Or to ask indeed is to pray, but to seek is by good works to do things becoming our prayers. And to knock is to continue in prayer without ceasing.”
