Not by Heaven Alone: Between the Iron Dome and Heartfelt Prayer

In times of war, when the Jewish People live under sustained threat and their enemies seek their destruction, it is only natural that words of chizuk should focus on the power of prayer. Indeed, it is hard to exaggerate its importance. Prayer reminds a person who he is. It returns us to humility, strips away the illusion that our own strength is the source of our salvation, and places us before Hashem as those who depend on Him at every moment.

The greater man’s power becomes, and the more advanced his technological and military capabilities grow, the greater the danger that he will forget this dependence on Hashem. In the face of that danger, the call to intensify our prayers — to pray more deeply, more brokenly, more earnestly — is both necessary and right. Such a call was recently issued by Rav Moshe Hillel Hirsch, shlita, in remarks published in the media. His emphasis was on the fact that “everything is from Hashem”:

“Regarding our situation here, there is a feeling that there is a lack of belief among the tzibbur in the power of tefillah — we are not feeling it enough…. Tefillah must be with the sense that nothing good happens except through Hashem. Everything that is called ‘natural,’ supposedly because of scientific advancement — that is not really scientific advancement, it is nothing! Everything is Hashem!”

And yet, for precisely that reason, one must be careful not to displace prayer from its proper place. When prayer is presented not merely as the spiritual foundation that accompanies human action, but as a substitute for it; when systems of defense — interception, training, planning, combat — are described as though they possess little significance of their own, as though they are merely an outer shell while only prayer “truly” saves, the result is a conception fraught with danger: the peril of inaction. Moreover, it finds no support in Chazal, in the Rishonim, or in the Torah’s basic orientation toward life in this world.[1]

The problem does not lie in the claim that everything comes from Hashem. That is a foundational truth, taught by our sages and articulated powerfully, among others, by the Ramban. The problem lies in the assumption that, in order to attribute salvation to Hashem, one must diminish the value of the means through which that salvation arrives. As though saying that an air-defense system saves lives somehow weakens faith. As though acknowledging that soldiers, pilots, engineers, and weapons systems play a real role in Israel’s defense means abandoning the conviction that “we have none upon whom to rely but our Father in Heaven.”

But the opposite is true. This is precisely the work of faith: to see the hand of Hashem within the means, not beyond them; to recognize that He acts in the world through strength, intelligence, discipline, courage, and human effort, not only where all of these are absent.

Chazal expressed this with striking precision. In Maseches Niddah (70b), the people of Alexandria ask Rabbi Yehoshua: “What should a person do to become wealthy?” He replies: “He should engage much in commerce and conduct his business faithfully.” When they object that many have done so and not succeeded, he adds: “Then let him ask for mercy from the One to whom wealth belongs.” The Gemara proceeds to conclude: ha b’lo ha lo sagi — one without the other is not enough.

Prayer does not come to displace action, and action does not come to render prayer unnecessary. Together, the two form the proper pattern of life.

This is no passing remark. It is a fundamental statement about the structure of Jewish life. Not only in livelihood, but also in wisdom, begetting children, and other earthly matters (as the Gemara notes), Chazal teach a model that joins derech eretz with prayer, effort with supplication, human action with turning toward Heaven. A person must act, and then — or, more precisely, while acting — he must pray. Prayer does not come to displace action, and action does not come to render prayer unnecessary. Together, the two form the proper pattern of life.

The verse does not seek to erase human causality, but to frame it. It does not deny human power; it restores that power to its source. Man acts, plans, initiates, exerts himself, struggles, and at times succeeds — and all of this because Hashem gave him strength, knowledge, wisdom, and opportunity.

From here, the weakness becomes clear in any conception that treats hishtadlus as little more than a tax one is forced to pay. To be sure, such a strand exists within Jewish tradition. The Ramchal, following Chazal’s teaching that a person’s livelihood is fixed for him from Rosh Hashanah, describes hishtadlus as a kind of universal human penalty: not because it truly produces results, but because toil was decreed upon man after the sin. Yet the further this line is pressed, the harder it becomes to sustain — not only from the standpoint of common sense, but also in light of halachah and lived reality. Indeed, nobody actually lives this way. No one chooses a profession without considering what it earns. No family facing financial strain refrains from seeking practical ways to increase its income. No doctor attempts to heal by bitachon alone, and no hungry person regards the search for food as a lapse in faith.

The Ran, in his derashot, offers a direct and deeply faithful reading of the verse: “For it is He who gives you the power to make wealth.” Not that Hashem makes the wealth in your place, but that He gives you the power to make it. This is an ironclad principle. The verse does not deny human causality; it situates it. It does not erase man’s power; it roots it. Man acts, plans, initiates, labors, struggles, and sometimes succeeds — and he does so because Hashem granted him strength, intelligence, wisdom, and opportunity.

In other words, faith does not require us to deny the tangible, but only to deepen it. Not to say that the soldier is not really fighting, or that his fighting makes no difference, but to understand Who gave him his strength. Not to say that the doctor does not heal, but to know Who placed wisdom in his heart. Not to say that the defense system does not intercept, but to thank the One who enabled human beings to acquire the knowledge and skill to build it. If attributing everything to Hashem means denying that means actually work, then one loses not only the world, but Hashem’s presence within it.

The Rambam’s sharp words in his commentary to the Mishnah (Pesachim 4:9) sharpen the point still further. He dismisses with open scorn the view that reliance on medical remedies reflects a deficiency in bitachon. In his eyes, anyone who says this is simply a fool. Just as no one refrains from eating on the grounds that Hashem is the One who feeds and sustains, so no one refrains from medicine on the grounds that Hashem is the Healer of all flesh. Food and medicine are the means Hashem implanted in the world for human sustenance and healing. To reject them in the name of faith is not trust. It is absurdity.

It is hard to imagine a clearer formulation of the proper relationship between faith and nature. From here, the move to questions of war and security is very short indeed. If, in relation to hunger, one may not say, “It is not bread that nourishes, but Hashem,” in a way that empties bread of its role, and if, in relation to illness, one may not say, “It is not medicine that heals, but Hashem,” in a way that empties medicine of its efficacy, then all the more so one may not say of war and defense: it is not these means that save, but only prayer.

Prayer is indispensable. Hashem, indeed, is the One who saves. But His salvation comes through the means with which He has endowed us. To sever that connection is to create a religious world increasingly incapable of bearing real responsibility for life in this world.

This becomes especially clear when one moves from abstract thought to the language of halachah, where the matter becomes almost self-evident. The Rambam rules in Hilchos Shabbos (2:23): “In every place, if they come on account of lives, or if they wage war, or if they lay siege even without specific intent, one goes out against them with weapons and desecrates Shabbos on their account.” Not only that, but “it is a mitzvah upon all Israel who are able to come and go and help their brothers who are under siege and save them.”

A healthy society must honor those who shoulder the burden of defense and combat. None of this is “nature” is in some sense opposed to faith. It is part of the Torah’s way.

This halachah expresses a basic truth — and, in fact, one obvious to all of us. When lives are in danger, the Jew does not suffice with prayer. He takes up arms, goes out, violates Shabbos, and saves lives in practice. Not as a concession away from Heaven, but as obedience to Heaven.

It thus becomes clear how mistaken it is to treat human action in matters of national security as something marginal, or at best grudgingly tolerated. It is part of avodas Hashem itself. The State of Israel is charged with defending its citizens. The IDF must be strong, professional, prepared, and well-trained. Protective systems must be sophisticated and precise. A healthy society must honor those who shoulder the burden of defense and combat. None of this is “nature” is in some sense opposed to faith. It is part of the Torah’s way.

Indeed, the Torah does not merely command war; it gives war a religious frame. It speaks of the sanctity of the camp, of the prohibition against fear grounded in the knowledge that “Hashem your God goes with you to fight for you,” and of the obligation to understand battle itself as part of a moral and religious struggle. The Rambam formulates this in his well-known words: “Once he enters the bonds of battle, he should lean upon the Hope of Israel and its Savior in time of distress.” Not before entering battle, and not instead of entering it, but once he enters. Man enters the bonds of war, and through that very act leans upon Hashem. This is the full picture: complete human action, and complete dependence on God, at one and the same time.

***

The problem, then, is not the call to strengthen prayer as such, but the way that call is sometimes framed. There is indeed a grave spiritual danger in overreliance on means. A society that grows accustomed to seeing technology as all-powerful may forget human fragility, the limits of power, and the fact that man never fully controls his own fate. Specifically in times of military success — of precise interceptions, operational achievements, and intelligence triumphs — there is a deep need for gratitude, humility, and prayer.

But across from this danger stands another, and at times one no less serious: the habit of belittling human responsibility. This is not only an intellectual mistake; it is also a form of moral and civic education toward passivity. It can foster a society that struggles to appreciate those who do the work, that degrades the world of action, that grows suspicious of responsibility itself, and that may even come to see those who take upon themselves the burden of security as people who have somehow distanced themselves from divine protection. Instead of a mature religious life, capable of holding holiness and the mundane together, it produces a religiosity that depends on denying the mundane to defend the holy.

Iron Dome is not a substitute for prayer. But prayer is also not a substitute for Iron Dome. One without the other is not enough.

But this is not the Torah’s way. The Torah does not fear the world; it seeks to sanctify it. It does not retreat from human action; it seeks to guide it, elevate it, and reconnect it to its source. In economics, in medicine, and in war alike, Judaism does not call on man to deny the tools in his hand, but to use them in faith: not to trust in them as though they were gods, but neither to dismiss them as empty vanity. Rather, to use them as one who knows that they, too, are gifts from Heaven.

Iron Dome is not a substitute for prayer. But prayer is also not a substitute for Iron Dome. One without the other is not enough. That is precisely the Gemara’s formulation: ha b’lo ha lo sagi. The Jewish People need both synagogues and army bases, both the conviction that “Hashem is a man of war” and the willingness to fight His wars. Not because we believe less, but because we believe more — so deeply that we do not need to deny reality in order to attribute all of it to the One who spoke and brought the world into being.

And so, in a time of war, the proper demand is not to choose between prayer and hishtadlus, but to restore their proper order: to increase prayer, and to increase hishtadlus; to ask mercy from the One to whom the war belongs, and to build the strength through which He saves. We must beware the illusion of “my strength and the power of my hand,” but we must beware no less the opposite illusion — that no human power truly acts at all.

Hashem saves Israel, “delivering us from their hand” as we note in the Haggadah. At times, He does so in hidden ways, at times in open ones, but (almost) always through human channels — through human hands. Faith does not require us to say that those hands do nothing. It requires us to know Who gave them their strength.
