If you've ever wondered what does the Bible say about fasting, you're not alone. Fasting is a spiritual practice mentioned throughout Scripture, yet many Christians today are unsure about its purpose, methods, or relevance. In this article, we'll explore the biblical foundation for fasting, what Jesus and the apostles taught, and how you can apply this ancient discipline to your modern faith journey. Whether you're a new believer or a seasoned Christian, understanding what the Bible says about fasting can deepen your relationship with God.
Biblical Foundations: Fasting in the Old Testament
The Old Testament presents fasting as a way to humble oneself before God, seek His guidance, or express repentance. One of the most significant examples is found in the book of Isaiah, where God speaks through the prophet about the kind of fasting He desires.
“Is not this the fast that I choose: to loose the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and to break every yoke?” — Isaiah 58:6 (ESV)
This passage reveals that true fasting is not merely abstaining from food but is coupled with acts of justice and mercy. Other Old Testament figures, such as Moses (Exodus 34:28), David (2 Samuel 12:16), and Esther (Esther 4:16), practiced fasting during times of crisis or spiritual seeking. Fasting was also a communal practice, as seen when the people of Israel fasted before battle or during national repentance (Judges 20:26; 1 Samuel 7:6).
New Testament Teachings: Jesus and Fasting
When we ask what does the Bible say about fasting, the teachings of Jesus are central. In the Gospel of Matthew, Jesus assumes His followers will fast, giving instructions on how to do it properly.
“And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that their fasting may be seen by others. Truly, I say to you, they have received their reward. But when you fast, anoint your head and wash your face, that your fasting may not be seen by others but by your Father who is in secret. And your Father who sees in secret will reward you.” — Matthew 6:16-18 (ESV)
Jesus emphasizes that fasting should be a private devotion between you and God, not a public display of piety. He also fasted Himself for forty days in the wilderness before beginning His ministry (Matthew 4:2), setting an example of relying on God's strength. In the early church, fasting was practiced during times of worship and decision-making, as seen in Acts 13:2-3 and Acts 14:23.
Practical Application: How to Fast Today
Understanding what does the Bible say about fasting is one thing; applying it is another. Here are some practical steps to incorporate fasting into your spiritual life:
- Start small: If you're new to fasting, begin with a partial fast (e.g., abstaining from one meal or a specific type of food) or a time-based fast (e.g., sunrise to sunset).
- Combine with prayer: Fasting is most powerful when paired with focused prayer. Use the time you would spend eating to pray, read Scripture, or meditate.
- Focus on God: The goal is not to earn favor but to draw near to God. Let your hunger remind you to seek Him.
- Be flexible: Fasting can take many forms—food, social media, or other distractions. The key is to set aside something that occupies your attention.
Remember, fasting is a tool, not a commandment. The Bible encourages it but does not mandate specific rules. Listen to the Holy Spirit and your body; if you have health concerns, consult a doctor before fasting from food.
Common Questions About Fasting
Is fasting required for Christians?
While the Bible does not command fasting as a requirement for salvation, Jesus' words in Matthew 6:16 imply it is a normal part of Christian life. It is a voluntary discipline for spiritual growth.
Can I fast from things other than food?
Yes. In 1 Corinthians 7:5, Paul speaks of abstaining from marital relations for a time to devote to prayer. Today, many Christians fast from technology, entertainment, or other distractions to focus on God.
Conclusion: Embracing Fasting as a Spiritual Discipline
So, what does the Bible say about fasting? It says that fasting is a humble, private act of devotion that draws us closer to God when done with the right heart. Whether you choose to fast from food, media, or other habits, let it be an opportunity to seek God's presence and align your life with His will. As you explore this practice, remember that God rewards those who earnestly seek Him.
