Frequently asked questions

What does the Bible say about fasting?

The Bible presents fasting as a spiritual discipline practiced by Moses, David, Daniel, Esther, and Jesus himself. Matthew 6:16-18 teaches fasting privately, focused on God rather than appearance. Isaiah 58 connects true fasting to humility, justice, and breaking spiritual chains, not just abstaining from food.

How do I start fasting as a Christian?

Start small: skip one meal and use that time to pray and read Scripture. Set a clear spiritual intention before God, drink water, and avoid sugar the day before. Most beginners do well with a 12 to 16-hour fast, building toward a 24-hour fast as they grow in the practice. Take care of your health, too: if you have a medical condition, are pregnant, nursing, or take medication, talk to a doctor before fasting.

What is the Daniel Fast and how does it work?

The Daniel Fast is based on Daniel 1 and 10, where the prophet refused royal food and ate only vegetables, fruits, grains, and water. It typically lasts 21 days, excluding meat, sweets, processed foods, and alcohol. It's a partial fast focused on spiritual clarity and devotion to God.

What can I eat during a biblical fast?

It depends on the type of fast. A complete fast involves only water. A Daniel Fast allows fruits, vegetables, legumes, whole grains, nuts, and water. It excludes meat, dairy, sugar, and processed foods. A partial fast may skip specific meals or restrict certain foods for a set period.

What should I pray about while fasting?

Use fasting to seek God's direction, repent, intercede for others, and grow spiritually. Pray for guidance on decisions, healing, family, breakthrough in struggles, and surrender to God's will. Each hunger pang becomes a reminder to turn back to prayer and Scripture.

How can an app help me fast and pray?

HolyFast is a Christian fasting app that brings your fasts together with daily prayer, Scripture reading, Bible studies, and devotionals. It sends prayer reminders during your fasting window so each hour becomes a moment of communion with God.

Why do Christians fast?

Christians fast to draw closer to God, seek His direction, repent of sin, and intercede in prayer. Fasting humbles the body so the spirit can focus on God's presence. Jesus assumed His followers would fast in Matthew 6:16 ("when you fast", not "if"), making it a normal part of Christian discipleship.
