A Guide to Christian Fasting

Fasting is a spiritual practice that has been a part of Christian tradition for thousands of years. It involves voluntarily abstaining from food or certain types of food for a period of time, often for spiritual purposes. While fasting may seem like an extreme or outdated practice to some, it holds significant importance in the Christian faith.

In this blog, we'll explore the concept of Christian fasting, its history and importance in the faith, and the different types of fasting. We'll also discuss the physical and spiritual benefits of fasting, and provide practical tips for preparing for and breaking a fast. Whether you're new to fasting or a seasoned practitioner, we hope this guide will be a helpful resource for you in your spiritual journey.

What is Christian Fasting?

Christian fasting is the voluntary abstention from food or certain types of food for a period of time, for spiritual purposes. Fasting is a way to deny ourselves earthly pleasures and desires and focus on God and His will.

There are different types of fasting, each with its own purpose and level of intensity. Here are some examples:

  • Absolute fast: Refraining from all food and drink for a period of time
  • Normal fast: Refraining from food but still drinking water or other liquids
  • Partial fast: Restricting certain types of food or drink, such as meat or sweets
  • Intermittent fast: Restricting food intake to certain hours of the day, such as eating only during an 8-hour window

Fasting is mentioned many times in the Bible, both in the Old and New Testaments. Some examples include:

  • Moses fasted for 40 days and nights before receiving the Ten Commandments from God (Exodus 34:28)
  • David fasted and prayed for his sick child (2 Samuel 12:16)
  • Esther and the Jewish people fasted to seek God's help in saving their people from destruction (Esther 4:16)
  • Jesus fasted for 40 days and nights in the wilderness before beginning His public ministry (Matthew 4:2)

Christian fasting is a powerful spiritual practice that can help us grow closer to God and align our hearts with His will.

Benefits of Fasting

Fasting has both physical and spiritual benefits. Here are some ways fasting can benefit us:

  1. Physical benefits: Fasting can improve our physical health by giving our digestive system a break and allowing our body to detoxify. Fasting has been shown to improve insulin sensitivity, lower blood pressure, and reduce inflammation.

  2. Spiritual benefits: Fasting can help us grow closer to God by allowing us to focus more on spiritual matters and less on physical desires. Fasting can help us develop greater self-control, humility, and dependence on God. By denying ourselves earthly pleasures, we can focus more on the eternal and cultivate a deeper relationship with God.

  3. Impact on other Christians: Fasting can inspire and impact the lives of other Christians. When we fast, we are bearing witness to our faith and showing others that we prioritize our spiritual lives. Additionally, fasting can bring us closer to our brothers and sisters in Christ as we share in the experience of seeking God together.

Examples of how fasting has impacted the lives of other Christians include:

  • Saint Augustine, a Christian theologian, fasted regularly as a spiritual discipline and wrote about its benefits in his writings
  • Martin Luther, the leader of the Protestant Reformation, fasted frequently and believed it was a way to discipline the body and focus on God
  • Corrie ten Boom, a Christian author and survivor of the Holocaust, fasted and prayed during her time in a concentration camp, and credited fasting as a way to maintain her faith and hope during difficult times

By incorporating fasting into our spiritual practice, we can reap both physical and spiritual benefits and make a positive impact on others.

How to Prepare for a Fast

Preparing for a fast is essential to ensure a safe and successful experience. Here are some practical tips for preparing for a fast:

  1. Seek God's guidance: Before beginning a fast, pray for guidance and discernment on what type of fast to undertake, how long to fast, and what spiritual goals to set.

  2. Set goals and expectations: Setting clear goals and expectations for a fast can help keep us motivated and focused. Consider what spiritual or physical benefits you hope to gain from the fast, and set realistic expectations for yourself.

  3. Plan ahead: It's important to plan ahead and make arrangements for the fast, especially if it involves abstaining from food for an extended period of time. Inform family and friends of your plans, and make sure to schedule any necessary appointments or activities around the fast.

  4. Gradual transition: It's important to gradually transition into the fast, especially if it involves a significant change in diet. Begin by gradually reducing your intake of certain foods, and make sure to stay well hydrated.

Examples of how to create a fasting plan include:

  • Choosing a specific type of fast, such as a 24-hour water-only fast or a week-long partial fast
  • Setting specific spiritual or physical goals for the fast, such as seeking clarity on a major decision or improving insulin sensitivity
  • Incorporating spiritual disciplines into the fast, such as prayer, meditation, or reading the Bible
  • Breaking the fast gradually, with simple and easy-to-digest foods such as broth or fruit, before returning to a regular diet

By preparing well and setting clear goals and expectations, we can have a safe and successful fast that brings us closer to God and reaps both physical and spiritual benefits.

How to Break a Fast

Breaking a fast is an important step that should be done gradually and safely to avoid health complications. Here are some tips for breaking a fast:

  1. Start with small meals: After a fast, it's important to start with small meals and gradually increase the amount and variety of food. Start with simple, easy-to-digest foods such as broth or fruit.

  2. Stay hydrated: It's important to stay hydrated during and after a fast. Start with small sips of water or other liquids, and gradually increase the amount over time.

  3. Avoid heavy or processed foods: After a fast, it's important to avoid heavy or processed foods that can be hard to digest. Instead, focus on nutrient-dense foods such as vegetables, fruits, and whole grains.

  4. Listen to your body: Pay attention to how your body reacts to different foods and adjust accordingly. It's important to listen to your body's signals and eat only what feels comfortable and nourishing.

Examples of foods to eat when breaking a fast include:

  • Broth or soup
  • Fresh fruits and vegetables
  • Whole grains such as quinoa or brown rice
  • Lean proteins such as grilled chicken or fish

Examples of foods to avoid when breaking a fast include:

  • Processed or fried foods
  • Heavy meats or dairy products
  • Sugary or highly processed snacks and desserts

By breaking a fast gradually and mindfully, we can avoid health complications and reap the full benefits of the fast.
