Why Do We Fast During Lent?

Wondering why we fast during Lent?

Fasting isn’t just about giving something up. It’s a choice to step back from the things that so often consume our attention. This allows us to refocus on what truly matters: our relationship with God.

When we choose to fast, we do more than merely deny ourselves pleasures or comforts; we actively open our hearts to God. This act of self-denial is not about rigid adherence to rules but a profound declaration of our dependence on Him above all else. Fasting cultivates trust as we lean on God’s strength rather than our own. It builds self-discipline, which strengthens our spiritual resolve, and deepens our capacity for love by prioritizing our spiritual relationship over worldly desires. Ultimately, fasting is our way of telling God that He is sufficient for us, that His grace and provision are all we need to live fully and richly.

But let’s be honest—fasting can be hard. It’s easy to forget, complain, or wonder if it really makes a difference. 

We’ll break it down even more, focusing on three main points: 

Fasting as an Act of Trust

The Freedom Found in Fasting

Fasting as a Pathway to Holiness

Fasting as an Act of Trust

From the very beginning of human history, God has called His people to obedience and trust—including in matters of food. In the Book of Genesis, Adam and Eve were given a command not to eat from a particular tree. This was not about deprivation but about trust in God’s wisdom.

“You may freely eat of every tree of the garden; but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall die.” (Genesis 2:16-17)

This first test in the garden echoes the discipline of fasting and abstinence today. Just as Adam and Eve were called to obedience, we are invited to embrace fasting as an act of trust in God’s plan.

Pope Benedict XVI reflected:

“Since all of us are weighed down by sin and its consequences, fasting is proposed to us as an instrument to restore friendship with God… the believer, through fasting, intends to submit himself humbly to God, trusting in His goodness and mercy.”

Rather than viewing fasting as a mere restriction, it can be seen as an opportunity—an invitation to renew a relationship with God by placing His will above our own desires.

The Freedom Found in Fasting

Beyond strengthening trust in God, fasting also cultivates spiritual freedom. In a world where instant gratification is the norm, it is easy to become attached to certain pleasures—whether food, entertainment, or other comforts. Without realizing it, these attachments can gain control over our lives.

Fasting disrupts this cycle. By voluntarily giving up food for a time, or abstaining from a particular indulgence, we practice self-mastery. This ability to say no to something small strengthens the will, making it easier to resist greater temptations.

A simple Lenten fast can lay the groundwork for deeper freedom from harmful habits, whether that be indulgent eating, gossip, or even more serious struggles like addiction to social media or pornography. The discipline gained through fasting extends beyond food; it equips the soul with the strength to reject sin and choose virtue.

A Pathway to Holiness

When Jesus began His public ministry, He fasted in the desert for 40 days. He did not do this to punish Himself but to prepare for His mission, relying on the strength of His Father. In the same way, when Catholics fast, they follow Christ’s example, allowing themselves to be formed by the discipline of sacrifice.

Fasting reminds us that we are made for holiness. When approached with the right disposition, it becomes an act of love, a way to reorder our desires and place God first.
