Luke 11:9

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.

(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.

Now he who promises any thing ought to convey a hope of the thing promised, that obedience may follow commands, faith, promises. And therefore he adds, For every one that asketh receiveth.

(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 shows 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.

(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.) 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?
