We have already spoken of the need that prompts Him to give this admonition and should prompt us to ask. Once you have the Word of God right and have made a good start in both doctrine and life, then inevitably temptation and opposition arise, not one kind but thousands of kinds. In the first place, there is our own flesh, that rotten old bag. It quickly becomes bored, inattentive, and indifferent to the Word of God and the good life. Thus we always have less of wisdom and of the Word of God, of faith and love and patience, than we should. This is the first enemy hanging around our neck so heavily every day that he keeps dragging us that way. Next comes the second enemy, the world. It begrudges us the dear Word and faith and refuses to put up with anything in us, no matter how weak we may be. It goes ahead and condemns us, it tries to take away what we have, and it gives us no peace. (Luther’s Works, v. 21, pages 230).

Our own desperate need should be enough to make us pray. But in addition, as though that were not enough, He seeks to draw us to it by means of the beautiful analogy of every father’s relation to his son. Though the son may be a good-for-nothing scamp, still he will not give him a serpent when he asks him for a fish. From that he draws these consoling words: “If you can do this, though you do not have a good nature or a single good trait in comparison with God, will not God, your heavenly Father, whose nature is completely good, give you good things if you ask Him for them?” This is the most sublime attraction by which anyone can be persuaded to pray, if we just looked at these words and took them to heart. (Luther’s Works, v. 21, pages 230).

Therefore every Christian should pay attention to this admonition. It is, in the first place, a commandment, as much as the previous statement, “Judge not” is a commandment. He should know that he is obliged to practice this Christian work. He should not be like that peasant who said: “I give grain to my minister, and he prays for me”; or like the people who think: “What is the use of my praying? If I do not pray, others do.” We must not suppose that it is no concern of ours or that it is left up to our free choice; but I have given more detailed admonition on this elsewhere.¹⁵ In the second place, you have here the comforting promise and rich assurance that He attaches to prayer, to make it evident that He cares about it and to teach us to think about prayer as something dear and precious before God, because His admonition is so serious and His invitation so friendly, and He promises that we shall not ask in vain. Even if we had no other reason or attraction than this rich and friendly word, it should be enough to prompt us to pray. I shall not even talk about how dear His exhortation is or how sublime His command or how desperate our need. (Luther’s Works, v. 21, pages 229-230).
