Should Christians Fast Today?

Published September 2, 2026

Should Christians fast today? Yes. Jesus indicated that His disciples would fast after His departure, and the New Testament church practiced fasting with prayer. However, Scripture does not command every Christian to follow one fixed schedule or prove spirituality through lengthy fasts. Fasting is a voluntary discipline that should be sincere, Christ-centered, and guided by wisdom.

Jesus Expected His Disciples to Fast

When people asked why His disciples were not fasting, Jesus compared Himself to a bridegroom. It was inappropriate for wedding guests to mourn while the bridegroom was present. Then He said, “the days will come, when the bridegroom shall be taken from them, and then shall they fast” (Matthew 9:15).

Jesus’ words point beyond His earthly ministry. After His death, resurrection, and ascension, His followers would experience seasons of longing, dependence, and serious prayer. Fasting would have a place in their lives as they awaited His return and served Him in a fallen world.

Jesus also said, “Moreover when ye fast,” not “if ye fast” (Matthew 6:16). He corrected hypocritical motives rather than abolishing the practice. His teaching assumes that fasting can be part of sincere devotion when it is directed toward God instead of human praise.

The Early Church Practiced Fasting

Acts gives clear evidence that fasting continued after Christ’s ascension. At Antioch, prophets and teachers “ministered to the Lord, and fasted” (Acts 13:2). During that time, the Holy Spirit directed the church to set apart Barnabas and Saul. The believers then fasted, prayed, laid hands on them, and sent them out (Acts 13:3).

Paul and Barnabas later appointed elders in churches “with prayer and fasting” (Acts 14:23). These examples connect fasting with worship, ministry decisions, and dependence on God. The practice was not limited to Old Testament Israel.

Fasting Is Not a Requirement for Salvation

No one is saved, justified, or made acceptable to God by fasting. The Pharisee in Jesus’ parable boasted, “I fast twice in the week” (Luke 18:12). Yet his religious record did not make him right with God. The repentant publican, who pleaded for mercy, went home justified rather than the self-righteous Pharisee (Luke 18:13–14).

Salvation is by grace through faith in Jesus Christ, not by works (Ephesians 2:8–9). Fasting cannot pay for sin or add merit to Christ’s finished sacrifice. A Christian fasts because he or she already belongs to Christ, not to earn a relationship with Him.

Fasting Is Not a Test of Spiritual Superiority

Christians should not judge one another according to the length or frequency of their fasts. The New Testament does not establish a universal weekly, monthly, or annual fasting schedule for the church. A believer who fasts should not despise one who does not, and a believer who does not fast should not ridicule sincere fasting.

Colossians 2:20–23 warns about man-made religious rules and severe treatment of the body that appear wise but cannot conquer sinful desires. Self-denial has value only when it supports obedience to Christ. Hunger by itself does not produce holiness.

When Might a Christian Fast?

Christians may choose to fast during seasons that deserve unusual focus in prayer. Examples include:

These situations do not force God to give the answer a person wants. They provide an opportunity to set aside ordinary comforts and seek Him with concentrated attention. Christians should continue praying according to God’s will.

Fasting Should Be Joined with Prayer and Scripture

A fast should create room for focused devotion. If someone skips meals but fills the time with ordinary distractions, the central spiritual purpose is weakened. The believer can use meal times to pray, read Scripture, confess sin, worship, and intercede for others.

Intercession is especially appropriate during a fast. A Christian may keep a written list of people and needs, pray through biblical passages, and ask God for wisdom about practical action. For more guidance, read What Is Intercessory Prayer?

Fasting Must Be Sincere and Discreet

Jesus warned against looking miserable so other people would notice a fast. He told His disciples to anoint the head and wash the face so they would not appear to be fasting (Matthew 6:16–18). The Father sees what is done in secret.

Secrecy does not forbid all corporate fasting. The church at Antioch fasted together, and a family or congregation may agree to do the same. It also may be necessary to explain a fast to a spouse, physician, or person preparing meals. Jesus condemned spiritual showmanship, not honest communication.

Fasting Cannot Replace Obedience

Isaiah 58 rebukes people who fasted while mistreating others and pursuing selfish interests. God called them to loose the bands of wickedness, relieve oppression, feed the hungry, and care for those in need. Their religious activity could not hide an unrighteous life.

A Christian should therefore examine motives and conduct. Fasting is empty when used to avoid forgiveness, restitution, generosity, sexual purity, truthful speech, or other clear commands. It should help believers pursue obedience, not create a substitute for it.

Christians Should Use Wisdom about Health

The Bible records extraordinary fasts, but believers should not imitate every detail carelessly. Physical needs, work demands, age, medication, pregnancy, chronic illness, and a history of disordered eating may affect whether or how someone can fast. A person with health concerns should seek appropriate qualified guidance.

Choosing a shorter fast or not fasting from food is not necessarily unbelief. God does not require reckless behavior. A Christian who cannot safely abstain from food can still devote extra time to prayer, Scripture, worship, and self-denial without claiming that personal discipline is a biblical food fast.

How Often Should Christians Fast?

Scripture gives no mandatory frequency for every believer. The Pharisees developed regular patterns, but Jesus never commanded His church to fast twice each week or on a particular calendar. The appropriate frequency will depend on spiritual purpose, personal circumstances, and wise conviction.

Some Christians may fast periodically. Others may fast mainly during particular crises or ministry decisions. The goal is not to accumulate impressive numbers. A short, sincere fast directed toward God is better than a long fast motivated by pride or pressure.

What Should a Christian Expect from Fasting?

Fasting may sharpen attention, expose dependence on comfort, deepen prayer, and help a believer humble the heart. Nevertheless, it does not guarantee a vision, special revelation, immediate emotional experience, or the exact answer requested.

God remains sovereign. Sometimes He grants the desired outcome. At other times He changes the believer’s understanding, gives strength to endure, or redirects the request. The fast is successful when it honors God and produces faithful dependence, even if circumstances do not change quickly.

Fasting Should Point to Christ

Christian fasting is shaped by the absence and promised return of the Bridegroom. Believers seek Christ, depend on His grace, and long for the day when faith becomes sight. Fasting should therefore increase love for Him rather than confidence in personal discipline.

Conclusion

Should Christians fast today? Yes. Jesus expected His disciples to fast, and the early church practiced it. Yet fasting is not required for salvation, governed by one universal schedule, or proof that one believer is more spiritual than another. It should be voluntary, prayerful, discreet, wise, and joined with obedience.
