Should Christians fast today? Yes, it’s a practice worth embracing. The Bible never gives a rule for how often to fast, but Jesus assumed his followers would do it, and the early church fasted regularly. Fasting means intentionally setting aside something we normally rely on, usually food, to focus our hearts on God. It isn’t a way to earn his favor. It’s a way to make room for him.
Fasting Runs Throughout the Bible
Fasting is a timeless spiritual practice. Moses fasted for forty days and nights on Mount Sinai when he received the law (Exodus 34:28). David fasted and pleaded with God when his infant son was sick (2 Samuel 12:16). Prophets, kings and ordinary people fasted in times of grief, repentance and urgent need. In the New Testament, Jesus talked about fasting in a way that shows he expected it to be a normal part of life with God.
Matthew 6:16-18 “When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show others they are fasting. Truly I tell you, they have received their reward in full. But when you fast, put oil on your head and wash your face, so that it will not be obvious to others that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you.
Notice that Jesus said “when you fast,” not “if you fast.” His concern wasn’t whether his followers would fast but why. Fasting to impress people misses the point. Fasting to draw near to our Father who sees in secret is exactly what he invites.
Fasting Helps Us Hear the Holy Spirit
The book of Acts shows the early church fasting as a regular part of worship. At a key turning point, the leaders of the church in Antioch were worshiping and fasting together when the Holy Spirit spoke clearly about what he wanted them to do next.
Acts 13:2-3 While they were worshiping the Lord and fasting, the Holy Spirit said, “Set apart for me Barnabas and Saul for the work to which I have called them.” So after they had fasted and prayed, they placed their hands on them and sent them off.
That moment launched Paul’s missionary journeys and the spread of the gospel across the Roman world. Fasting doesn’t force God to speak, but it quiets the noise of our appetites and distractions so we are better able to notice his leading. The Spirit usually guides through convictions and nudges that line up with Scripture, and fasting helps tune our hearts to recognize them, especially when we face a big decision or a new calling.
You don’t have to be a church leader to experience this. Many believers set aside a day to fast and pray before a job change, a move, a difficult conversation or a season of ministry. They often find that the clarity they were looking for came not from the fast itself, but from the focused time they spent listening to God.
Fasting Strengthens Us for Spiritual Battles
Before Jesus began his public ministry, he spent forty days fasting in the wilderness. There he faced the devil’s temptations head-on, and his response shows what fasting is ultimately about.
Matthew 4:1-4 Then Jesus was led by the Spirit into the wilderness to be tempted by the devil. After fasting forty days and forty nights, he was hungry. The tempter came to him and said, “If you are the Son of God, tell these stones to become bread.” Jesus answered, “It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God.’”
When we fast, we feel our weakness in a very physical way, and that hunger becomes a reminder to depend on God rather than ourselves. Fasting can strengthen our resolve against temptation and help us pray with greater urgency when we face spiritual battles. It teaches us, in our bodies, that God’s grace is what truly sustains us.
Should Christians Fast? How to Start Wisely
Through the prophet Isaiah, God rebuked people who fasted while ignoring injustice and mistreating others. Real fasting, he said, should change how we treat people.
Isaiah 58:6-7 “Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke? Is it not to share your food with the hungry and to provide the poor wanderer with shelter—when you see the naked, to clothe them, and not to turn away from your own flesh and blood?
If you’re new to fasting, start small. Skip one meal and spend that time in prayer, or fast from social media, television or another habit for a day. Anyone with diabetes, a history of eating disorders, a pregnancy or another medical condition should talk with a doctor before fasting from food and may choose a non-food fast instead. The goal isn’t to prove your toughness but to make space for God and let him shape your heart.
The Takeaway
Should Christians fast? Jesus expected his followers to fast, and the early church found that fasting helped them hear the Spirit, prepare for their calling and fight spiritual battles. Start small, fast with the right motives, and let your hunger remind you to depend on God.
