Biblical Accounts of Jesus's Fasting
The most detailed accounts of Jesus's 40-day fast are found in the Gospels of Matthew and Luke. Both describe his time in the wilderness and the subsequent temptations by the devil. A close reading of the text provides important clues about what he consumed.
Luke's Explicit Statement
Luke 4:2 is particularly direct, stating that Jesus "ate nothing during those days, and when they had ended, he was hungry". Notably, the verse does not say he also went without drink. This distinction between abstaining from food versus drink is critical for theological and physiological interpretations. The omission of any reference to thirst, paired with the explicit mention of hunger at the fast's conclusion, suggests that while he did not eat, he likely did drink.
A Look at Jewish Fasting Customs
To understand Jesus's fast, it is helpful to consider the typical fasting customs of his time. Jewish practice recognized different types of fasts, including food-only fasts and absolute fasts where both food and water were abstained from. Absolute fasts were typically shorter, lasting no more than a few days, while fasts from food alone could be more extended. The fact that Jesus's fast lasted 40 days supports the conclusion that it was a food-only fast, consistent with Jewish tradition and human physiology.
Theological and Symbolic Interpretations
The 40-day duration of Jesus's fast holds significant biblical symbolism, echoing other pivotal moments of testing and spiritual preparation in scripture. This period is a powerful testament to Jesus's humanity and his complete reliance on God the Father.
- Echoing Moses and Elijah: The 40-day fasts undertaken by Moses and Elijah are key biblical parallels. In Exodus 34:28, Moses is recorded as having fasted from both food and water while in God's presence, an event suggesting miraculous divine sustenance. In contrast, Elijah was sustained by angelic provision for his 40-day journey. Jesus's fast places him in the lineage of these prophetic figures, but his reliance was on the Holy Spirit rather than external, miraculous food.
- Preparing for Ministry: The fast was a time of spiritual readiness before Jesus began his public ministry. By denying his physical needs, he heightened his spiritual focus, demonstrating his commitment to God's will. This period was not merely a physical challenge but a profound spiritual fortification.
- Overcoming Temptation: Satan's temptation to turn stones into bread specifically addresses Jesus's physical hunger. Jesus's response, quoting Deuteronomy 8:3, emphasizes that "Man shall not live by bread alone, but by every word that comes from the mouth of God". This victory over temptation while in a state of physical weakness showcases his spiritual strength and sets an example for believers.

Scientific Possibility and Theological Interpretation
From a purely physiological perspective, a human cannot survive 40 days without water, making Jesus's survival a subject of both rational and theological inquiry. While science defines the limits of human endurance, theology presents a different framework. For Christians, Jesus is understood as both fully human and fully divine. His endurance is not seen as merely a feat of human will but as a testament to divine power and grace. The miracle is not that Jesus broke physical laws, but that he was sustained by God's power in a state of profound spiritual focus.
For a deeper look into the human body's limits during fasting, particularly concerning hydration and starvation, one could consult medical resources like Healthline's article on the subject. This offers a secular perspective on the physiological realities that Jesus would have faced, highlighting the miraculous aspect of his survival without food.
Conclusion: The Spiritual Significance of Water
In the final analysis, the question of what Jesus drank during his fast leads to a deeper understanding of his spiritual journey. By drinking water, he maintained his humanity, yet by abstaining from food, he showed supreme spiritual discipline and reliance on God. His victory over temptation, achieved through spiritual strength rather than supernatural power, serves as an enduring model for believers. It underscores that fasting is not about punishing the body, but about preparing the spirit and prioritizing communion with God above physical comforts. The simple act of drinking water during his fast allows for a relatable parallel to our own spiritual journeys, reminding us that even in profound spiritual moments, we operate within the bounds of human reality while trusting in divine provision.
