Fasting is practised by Christians as a form of devotion that often involves abstaining from food while praying, worshipping and seeking God’s guidance. Biblical accounts describe individuals and early Christian communities fasting at important moments, including periods of prayer, repentance and decisions about ministry.
The New Testament contains several examples of the practice, although the passages do not prescribe one universal fasting routine for all Christians.
In Matthew 4:2, Jesus fasted for 40 days and 40 nights in the wilderness before the events that preceded his public ministry. In Luke 2:37, Anna, a prophetess who worshipped at the temple, is described as fasting and praying regularly.
The book of Acts also records fasting among early Christian leaders. Acts 13:2-3 describes members of the church at Antioch worshipping and fasting before Barnabas and Saul were commissioned for their work. In Acts 14:23, Paul and Barnabas prayed and fasted when appointing elders in local churches.
These passages present fasting as part of religious devotion and decision-making. Christians interpret its spiritual significance in different ways, including as a means of seeking God’s direction, expressing dependence on Him and strengthening their commitment to prayer.
Fasting, repentance and forgiveness
Fasting also appears in biblical accounts of repentance and appeals for mercy. In Daniel 9:3, Daniel turns to God in prayer and petition, accompanied by fasting, sackcloth and ashes.
The passage forms part of Daniel’s prayer of confession and his appeal for God’s mercy on behalf of his people.
For many Christians, such accounts provide a basis for incorporating fasting into periods of repentance and spiritual reflection. However, the Bible does not present abstaining from food as a substitute for repentance or as an automatic guarantee of forgiveness.
Christian teaching generally places fasting within a broader relationship with God that includes prayer, faith and a change in conduct.
The New Testament book of Hebrews discusses faith, Christ’s role as high priest and the hope of eternal life, but it does not explicitly identify fasting as a means of securing salvation. Similarly, the account of the early church in Acts contains examples of fasting and prayer but does not describe a ten-day period of fasting prescribed for all believers.
How early Christians used fasting
The account in Acts 13 shows a community fasting while worshipping before receiving what the text describes as guidance from the Holy Spirit concerning Barnabas and Saul.
After the period of fasting and prayer, the community laid hands on the two men and sent them on their mission.
Acts 14:23 records another occasion when Paul and Barnabas appointed elders in the churches and committed them to the Lord through prayer and fasting.
These accounts illustrate how fasting was practised collectively as well as individually. They also show its connection with specific decisions and responsibilities within the early Christian community.
In Luke 2:37, Anna’s regular fasting and prayer are associated with her devotion to worship at the temple. Matthew 4:2, meanwhile, records Jesus’ prolonged fast in the wilderness.
The circumstances differ, but the passages have become important references for Christians seeking to understand the practice.
Prayer and practical considerations
Fasting is commonly combined with prayer and Bible reading in Christian worship. Some believers also use the period to reflect on personal conduct, seek guidance or renew their commitment to their faith.
Christian traditions differ on how fasting should be observed, including its duration and whether it involves abstaining from all food or giving up particular foods. The biblical passages cited above do not establish a single schedule that applies to everyone.
Fasting should also be distinguished from practices intended to punish the body. Extended food restriction can pose health risks, particularly for young people and those with medical conditions. Anyone considering a fast that involves going without food should seek appropriate guidance from a healthcare professional, especially where health or nutritional needs may be affected.
For Christians, the central purpose of fasting is generally understood through its relationship with prayer, worship and devotion to God. The biblical accounts provide examples of how individuals and communities incorporated the practice into their faith, while leaving differences in observance across Christian traditions.
