Why Do Jews Fast? A Powerful Perspective on Joy, Faith, and Jewish Identity

Anyone who observes the Jewish people and the historical fast days that return year after year may wonder why Judaism established so many days of fasting and remembrance. Seeing that the Jewish people did not settle for a single day to mourn the loss of their greatness in their land, one might conclude that what the nation needs above all is more fasting and more tears.

After all, one could argue that the disasters that have befallen the Jewish people throughout history stem from recklessness and moral permissiveness. If so, perhaps the goal of these fasts is to break the spirit of the people through mourning and self-denial, cultivating humility through suffering and preparing them for a better future through self-affliction and submission.

Yet nothing could be further from the truth.

The purpose of the historical fasts is entirely different.

Because We Rejoiced Too Little

The tragedy of Jewish history did not occur because we laughed too much and cried too little during times of prosperity.

Rather, it occurred because we laughed too little and cried too much.

It was not because we were overly carefree, but because we were too fearful. Our confidence in the destiny of the Jewish people and in our unique mission was too weak. We viewed ourselves as small in comparison to the great nations with whom we came into contact throughout history.

And because we underestimated ourselves, we were swept into the currents of history instead of shaping them.

The historical fast days were not established to fill us with despair or depression. Their purpose is to show us the path from the depths of national destruction toward joyful self-awareness, renewed vitality, and a flourishing life dedicated to God.

Fasts Lead to Joy

The prophet Zechariah declares: "The fast of the fourth month, the fast of the fifth month, the fast of the seventh month, and the fast of the tenth month shall become for the House of Judah joy, gladness, and cheerful festivals; therefore love truth and peace." (Zechariah 8:19)

Perhaps the deeper message of this verse is precisely that Jewish life is meant to be characterized by joy, vitality, and a healthy sense of national dignity.

We are meant to take pride in our unique role among the nations, not to live with fear, insecurity, or a constant need for justification.

The Great Historical Failure: Losing Confidence in Jewish Identity

The great failing that accompanied the Jewish people throughout much of their painful history was a lack of appreciation for the beauty and greatness of Judaism itself. The Jewish people often failed to recognize the joy that should accompany every aspect of Jewish life.

Was it not a lack of confidence in our destiny and mission that prevented the completion of the conquest and settlement of the Land of Israel?

Was it not fascination with Canaanite religion and culture that led to the shameful desire to be "like all the nations around us"?

When the people demanded a king who would "go out before us" and lead our battles, were they not forgetting that God Himself had led them out of Egypt and fought their wars?

What was this longing to be like everyone else if not an expression of insecurity and spiritual weakness?

"Because You Did Not Serve God With Joy"

The Torah teaches that many of Israel's sufferings came: "Because you did not serve the Lord your God with joy and gladness of heart."

How could it be otherwise?

If a Jew does not honor Judaism, if Judaism does not fill him with joy and elevated self-awareness, if it does not strengthen him to withstand the dazzling attractions of worldly power and temporary greatness, then why should others value it?

How can the nations appreciate Judaism if the Jew himself carries it reluctantly?

If he does not serve God with happiness and gratitude, if he constantly seeks to replace Jewish values with non-Jewish ones, or feels the need to add foreign ideals to Judaism, then he inevitably weakens both himself and the message he represents.

As long as: "We were like grasshoppers in our own eyes," the result will be: "And so we were in their eyes."

Seeking Approval From God or From People?

As long as we are not satisfied with the knowledge that God desires us, as long as we need the approval of others in addition to divine approval, we will never find true peace.

If a person's happiness depends not only on finding favor in God's eyes but also on gaining acceptance from society, then that happiness will always remain fragile. True joy comes when the awareness of God's favor is so powerful that no additional validation is needed.

The Torah presents God as a jealous God — not because of insecurity, but because He demands wholehearted commitment.

The prophet Elijah expressed this challenge clearly: "How long will you continue wavering between two opinions? If the Lord is God, follow Him; but if Baal, follow him."

A divided heart can never find lasting fulfillment.

What Is the Purpose of the Destruction — and of Remembering It?

The purpose of the destruction was not to humiliate the Jewish people or drive them into despair. Quite the opposite.

Its purpose was to strengthen the bond between the Jewish people and God by removing the false values that had been competing for our loyalty.

For centuries, exile left us with little besides God, His kindness, the joy of serving Him, and the pursuit of truth and peace. In that sense, the destruction itself became a tool of spiritual refinement.

The annual fast days serve the same purpose.

Why Are They Called "Fasts" Rather Than "Afflictions"?

The Torah uses the phrase: "You shall afflict your souls" only regarding Yom Kippur.

Yom Kippur is a day focused on atonement, purification, and recognizing our complete dependence on God's mercy. On that day we stand before God stripped of physical comforts and plead for forgiveness and renewed life.

But the historical fast days are called tzomot — fasts.

The root of the word tzom suggests gathering, concentrating, drawing inward, and bringing things together.

That is their true purpose. These fasts are intended to gather us back to the center of our Jewish identity.

They remind us who we are, even if every other social, political, or cultural identity were stripped away.

Returning to What Truly Matters

Historical fasts are intended to return us to the center of our moral and spiritual consciousness.

When we sit hungry and physically weakened, yet continue standing before God, we learn that our relationship with Him is not dependent on comfort, wealth, pleasure, or external success.

The central question becomes: "Does God desire us?"

This should not merely be our greatest concern — it should be our only concern. All other worries should be understood in relation to that one question.

Whether in hunger or abundance, weakness or strength, illness or health, disappointment or achievement, sorrow or joy, we are called to live our lives before God.

The Goal: Happier, Stronger, More Authentic Jews

The ultimate purpose of the historical fast days is not to make us sadder, but to make us better.

They are meant to transform us into more authentic and more joyful Jews — people who serve God with happiness and gladness of heart, who find their deepest fulfillment in that service, and whose highest goal is to live according to the truth He has revealed.

The fasts are not monuments to despair. They are invitations to rediscover confidence, purpose, joy, and faith. Through them, we are reminded that Jewish identity is not a burden to be carried reluctantly, but a privilege to be embraced with pride, gratitude, and happiness.
