Understanding what the Bible says about fasting isn’t complicated, but a lot of Christians still struggle with what it actually means and how it fits into their lives.
In the New Testament, fasting simply means going without food for religious reasons. It’s something followers of Jesus did to grow closer to God. The Bible also shows that fasting connects to being cleansed by the Holy Spirit and receiving forgiveness for sins. It’s not just a ritual — it’s part of the journey toward deeper salvation and spiritual progress.
Fasting isn’t random either. There’s a real purpose behind it. God’s grace is available to everyone, but fasting helps believers tap into that grace in a powerful way. Since we’re created in God’s image, we were made to have a close relationship with Him. When we spend time fasting and praying, we allow God to clean our hearts, forgive our sins, and strengthen our bond with Him.
One of the first places we see fasting explained is in the New Testament book of Hebrews. It shows that fasting is tied to the hope of eternal life. Another place is the book of Acts, where the early church leaders called their people to fast. They even set aside ten days specifically for fasting and prayer.
The Bible gives plenty of examples too. In Matthew 4:2, Jesus fasted for 40 days in the wilderness before starting His ministry. In Daniel 9:3, Daniel fasted and prayed, wearing sackcloth and ashes as he sought God’s mercy. Luke 2:37 talks about Anna, a prophetess who fasted and prayed at the temple day and night. Acts 13:2-3 shows the church at Antioch fasting before sending Barnabas and Saul out to preach, and Acts 14:23 describes Paul and Barnabas fasting when they chose leaders for the churches.
During these fasts, people prayed, listened to the Holy Spirit, and asked for God’s help. Building that strong relationship with God leads to real change — He meets our needs, heals us, and guides us.
If you’re wondering how long you should fast, it often starts by changing your daily habits. You’ll notice yourself reaching for healthier, simpler foods. Even though you’re eating less, your spirit gets fed in a much bigger way.
While fasting, it’s important to stay spiritually connected. Speaking and praying in the Spirit opens your heart to hearing God’s voice more clearly. If we ignore what the Spirit is telling us, we miss out on the blessings God wants to give us.
It’s also smart to avoid things that might make you sick during a fast — no heavy desserts or salty junk food. Fasting isn’t about punishing yourself; it’s about tuning in to what God has prepared for you.
As you fast, remember that it’s always okay to ask God for help. In fact, we need to! Staying humble and prayerful keeps us in the right place to receive His strength.
If you’re looking for more help, there are lots of books that recommend Bible verses to read during a fast. They often focus on the spiritual benefits, like growing closer to God and breaking through struggles.
When we fast spiritually, it’s not just our bodies that get stronger — God also fights battles for us in the unseen world. Through fasting, the Holy Spirit works inside us, helping with everything we’re called to do.
Fasting and prayer go hand in hand in the Bible. Together, they help believers focus on God, seek His will, and show their love and devotion. It’s not just about skipping meals — it’s about letting God transform your heart and your life.
