When Gandhi wanted to capture the attention of the powerful and prompt them to act against injustice, he went on a hunger strike. A number of years ago when I was confused and heartbroken, I began a 3-day fast. We are physical creatures, and the state of our soul or the hopes of our heart require physical expression.

Scripture suggests that our use of (or refraining from the use of) food is a natural and expressive way that our body reflects the spiritual realities we experience. Scripture offers a myriad of causes that would prompt our fasting from food, but the underlying theme is that our fasting is a response to God. Some of the reasons we might turn to God in fasting include the following:

• A tragedy has struck, and we turn to God in sorrow. For instance, when David mourned the death of Saul and Jonathan (2 Samuel 3:35).

• A purposeful way of attuning ourselves to God, remembering that God’s presence is what we most crave. Biblical fasts concluded with feasts, declaring that those who are hungry for God are filled.

• An act of solidarity with the poor. Through the prophet Isaiah, God told Israel that the fasting He desired would result in sharing their “food with the hungry” (Isaiah 58:7). Augustine asked this penetrating question: “How many poor can be filled with the breakfast we have this day given up?”

We can fast for these reasons and many more. Each allows us to physically obey God, to physically pay attention to Him, to seek God with our mouth and our stomachs—all our human sensations. In fasting, we encounter God with our bodies.
