Fasting
Going without food — or something else — for a set time as a spiritual practice, usually paired with prayer, to focus on God and express dependence on Him.
What they actually mean
“"Skipping food on purpose, to pray better and want God more."”
Heard in the wild
“I'm fasting from lunch on Wednesdays this month.”
“The church is doing a 21-day fast in January.”
The Lighter Side
Skipping food on purpose to focus on God. Frequently the moment you discover how much of your spiritual life was actually just snacks.
The longer version
What it means
Fasting is deliberately going without — food, most traditionally, but also other things — for a period, in order to pray, seek God, repent, or simply remember that you depend on Him more than on your next meal. A fast might be one meal, a day, or longer; it might be total or partial; it might be individual or the whole church together ("a corporate fast"). Christians usually pair the skipped meal with the time it frees — praying instead of eating.
Modern churches also speak of fasting from screens, shopping, or news, applying the principle to whatever crowds God out.
Why people say it
Jesus fasted forty days, assumed His followers would fast ("when you fast," not "if"), and told them to do it privately. The early church fasted before big decisions. Fasting makes hunger a reminder to pray; it exposes how much you lean on comfort; and it's a physical way of saying "I want You more than this." Christians who practice it say it sharpens prayer in a way nothing else does.
How to respond
If someone tells you they're fasting, don't offer them food, and don't make it awkward; "how's it going?" is fine. If they're fasting from something other than food, it's the same idea, and the same response. If a church you attend announces a corporate fast, you're invited, not required, and partial participation is normal. If someone's fasting seems extreme or tied to weight, a gentle question about how they're doing is appropriate.
If you hear it in different churches
Orthodox Christians fast the most: Wednesdays and Fridays year-round and four long fasting seasons, abstaining from meat, dairy, and often oil and wine. Catholics fast on Ash Wednesday and Good Friday and abstain from meat on Lenten Fridays; older Catholics remember meatless Fridays year-round. Anglicans and Lutherans keep Lent with varying strictness. Evangelicals and Pentecostals fast for prayer and revival, often in January ("21 Days of Prayer and Fasting"). Mainline Protestants fast least.
Where does “Fasting” come from?
Moses, David, Esther, Daniel, and Nehemiah all fast; Isaiah 58 insists that a fast God accepts includes justice for the poor. Jesus fasts in the wilderness and teaches on it in the Sermon on the Mount. The Antioch church fasts before sending Paul and Barnabas (Acts 13). The Didache (around AD 100) already prescribes Wednesday and Friday fasts, which the Orthodox keep. Lent as a forty-day fast was established by the 300s. The Reformers kept fasting but rejected mandated fast days; evangelical revivalism revived it for prayer, and the "Daniel fast" and "21 days" formats are twenty-first-century American developments.
Good to know
Christian fasting is not dieting and not self-punishment; the point is prayer and dependence. Forms range from a full fast (water only) to a partial fast (one meal a day, or the "Daniel fast" — vegetables, no meat or sweets) to fasting from something other than food (social media, TV). Anyone with a medical condition, an eating disorder history, or a pregnancy should skip food fasts, and any responsible church will say so.

Lent
Prayer & DevotionThe roughly forty days before Easter, from Ash Wednesday to Holy Saturday, kept as a season of repentance, fasting, and preparation — often by giving something up.
“"The forty days before Easter when you give something up and take faith more seriously."”
Ash Wednesday
Holidays & CalendarThe first day of Lent, marked by a cross of ashes on the forehead as a sign of repentance and mortality — "remember that you are dust."
“"The day Christians get a smudge on their forehead and keep it there on purpose."”
Common questions
Do you have to fast to be a Christian?+
No. Jesus assumed His followers would, and most traditions encourage it, but it's a practice, not a requirement, and those with health concerns are told not to.
What's a Daniel fast?+
A partial fast — vegetables, fruit, water, no meat, sweets, or rich food — based on Daniel 1 and 10. Popular in evangelical churches, usually for twenty-one days.
Can I fast from something other than food?+
Yes, and many Christians do — social media, TV, coffee. The principle is the same: give something up to make room for God.
