Fasting with a Biblical Purpose: A Three-Session Study

Begin with the purpose of the study

The assigned readings are Matthew 6:16–18, Isaiah 58, and Acts 13:1–3. Read each in full before using the commentary. They address different situations: Jesus’ instruction, a prophetic confrontation, and a narrative about the church at Antioch. Keeping those forms distinct prevents a single formula from replacing what each passage says.

In each session, ask four questions: who is addressed, what is being done, what purpose or problem is named, and what response follows? The questions direct attention toward the biblical text before your own plan or expectation. A practice can look serious while missing the purpose the passage brings into view.

This guide does not specify a fast’s length, foods, or frequency. None of the three assigned readings gives a universal timetable for this study to reproduce. You can complete every reading, question, prayer, and act of care here without undertaking food restriction. If abstaining from food would endanger your health, do not use the plan as a reason to do so.

Keep the focus on attention to God and conduct toward others. Measuring how much discomfort you can tolerate or how impressively you can describe it would work against the questions these passages ask. The practical exercises concern sincerity, mercy, prayer, and a faithful response.

Session one: notice the audience of devotion

Read Matthew 6:16–18. Jesus speaks about people who alter their appearance so that others will see that they are fasting. Their visible sadness and disfigured faces serve a social purpose: they want the practice to be recognized. Jesus says they have their reward.

The instruction redirects attention to the Father. Jesus tells the person fasting to anoint the head and wash the face, rather than turn appearance into an announcement. Ordinary care of the body becomes part of refusing a religious performance. The passage does not praise neglect of the body as proof of sincerity.

Read the instruction within Matthew 6:1–18 if time permits. Giving, prayer, and fasting are all addressed with concern for the audience and reward of devotion. The repeated question is whose recognition a person is seeking. This is more searching than a rule about whether someone happens to know that a practice occurred.

For personal reflection, distinguish being seen from acting in order to be seen. There may be ordinary reasons someone knows your plans. The passage challenges the use of devotion to cultivate admiration. It asks whether the Father remains the focus when no one else notices.

Practice sincerity without display

Jesus’ words can expose motives that are mixed rather than entirely false. A person may sincerely desire God while also hoping to be admired for spiritual seriousness. The useful response is honest attention, not a dramatic declaration that one has finally become free of every mixed motive.

Ask what would change if there were no opportunity to report the practice afterward. Would you still want to pray, listen, and respond? Would you feel cheated because no one saw the effort? These questions help identify the audience toward which your conduct is leaning.

The Father’s seeing should be received as part of the passage’s comfort. Hidden devotion is not lost because it does not produce a public record. At the same time, the promise of reward is not defined here as a particular promotion, healing, relationship, or answer on a chosen date. Do not fill the promise with details Jesus does not supply.

An original prayer might be: “Father, help me attend to You without making devotion a performance. Receive what is sincere, correct what seeks admiration, and teach me to care for my body and my neighbors truthfully. Let what is hidden before You shape the way I live when I am seen.”

Session two: hear Isaiah’s confrontation

Read Isaiah 58. The people seek God daily and ask why their fasting has not brought the attention they expect. The prophetic answer points to their conduct during the fast: pursuing their own pleasure, exacting labor, quarrelling, and striking with wickedness.

The problem is not a lack of visible religious effort. Bowed heads, sackcloth, and ashes are already present in the description. The chapter asks whether those signs can be called an acceptable day while the people continue to burden and harm others.

This makes the passage especially important for a study of purpose. Fasting cannot be isolated from the life around it. If a person’s observance is made possible by treating someone else unfairly, or if it becomes an occasion for irritability and contempt, the conduct itself needs attention.

Read the confrontation as an invitation to examine your own responsibilities before using it to judge someone else’s practice. The question is not whether you can identify a more hypocritical worshiper. It is whether you are willing to let devotion expose what needs to change in your treatment of people.

Let devotion reach mercy and repair

Verses 6–7 describe releasing wicked bonds, undoing burdens, freeing the oppressed, sharing bread, receiving the poor who are cast out, and clothing the naked. The chosen fast reaches both harmful arrangements and immediate need. It asks for more than a sympathetic feeling.

Verses 9–10 also address the yoke, the pointing finger, vain speech, and attention to the hungry and afflicted. Speech is part of the chapter’s moral world. A person can give something away while continuing to humiliate another person; the passage asks for a more coherent response.

The promises of light, guidance, a watered garden, and rebuilding appear within this call to changed conduct. They should not be presented as a price list in which a particular generous act purchases a desired blessing. The chapter confronts a relationship between worship and life, not a technique for managing God.

The closing Sabbath verses retain the honor of holy time and delight in the Lord. Isaiah’s concern for mercy does not dismiss worship. The chapter draws the reader toward devotion that is truthful in both its sacred practice and its treatment of neighbors.

Session three: observe the community at Antioch

Read Acts 13:1–3, then include verse 4. The narrative names prophets and teachers at Antioch, including Barnabas and Saul. They are ministering to the Lord and fasting when the Holy Spirit directs that Barnabas and Saul be set apart for the work to which He has called them.

The sequence matters. The community’s worship is already directed toward the Lord, and the Spirit’s word names the people and the work. The passage does not portray the group inventing a desired outcome and then fasting until that outcome is guaranteed.

Verse 3 describes fasting, prayer, the laying on of hands, and sending. Verse 4 then describes Barnabas and Saul as sent by the Holy Spirit. The narrative holds the community’s obedient action and the Spirit’s direction together. It gives no reason to diminish the laying on of hands as an empty gesture.

This is a particular event in the church’s mission. It can instruct a community to worship, pray, listen, and respond faithfully, while remaining a story with its own participants and commission. The text does not provide a mechanical test by which every strong impression during a fast becomes an authoritative message.

Connect listening with a responsible response

A community studying Acts 13 can ask how its attention is directed before it makes a decision. Is prayer being used to decorate a settled preference, or is there a willingness to hear something that changes the plan? The question should be asked humbly; the passage does not give an observer access to everyone’s private motives.

The narrative also moves from hearing to action. Barnabas and Saul are sent, and the next verse names their departure. Discernment is not presented as an endless accumulation of impressions with no willingness to respond. When a responsibility is clear, the community acts.

For a present decision, distinguish the facts you know, the counsel you have received, the responsibilities that are already clear, and the matters that remain uncertain. This exercise does not reproduce the authority of the Spirit’s speech in Acts. It helps prevent a personal preference from being presented as though it had that same explicit status.

An original prayer might be: “Lord, direct our attention toward You. Give us patience to listen, honesty about what we know, and courage for the responsibilities You have made clear. Keep us from using religious effort to force our preferences, and help us support those entrusted with work that serves others.”

Let Jesus’ teaching govern the purpose

Jesus' instruction in Matthew 6 gives this plan its direct center in His teaching. He turns the person fasting toward the Father who sees in secret and away from the pursuit of public recognition. Isaiah's call to mercy examines the conduct surrounding devotion, and Acts shows a community worshiping and responding to the Holy Spirit. Together these readings keep attention on God and on a faithful response. Following Jesus here includes sincerity that does not depend on applause and a willingness for devotion to shape the way we treat the people around us.

Review your purpose and practice

Return to the sentence you wrote at the beginning. Has your understanding of fasting’s purpose changed? Perhaps you began with a request for an answer and now also see a need for sincerity, changed conduct, or patient attention. Name the change without treating the study as proof that every question has been resolved.

Create a simple response from the three passages: one quiet practice before the Father, one act that addresses a burden or need, and one period of prayerful attention to a real responsibility. These exercises can be completed without food restriction. They are practical responses to the readings, not a claim that Scripture gives this exact three-part rule.

If you choose to discuss the plan with others, share observations from the text rather than comparing how demanding each person’s observance was. A useful conversation asks what the passages reveal about motives, mercy, and response. It does not require participants to disclose private practices or justify personal health decisions.

Finally, record what you actually did and what remains uncertain. Do not manufacture a dramatic result or treat an unanswered request as proof that the practice was insufficiently severe. The readings direct the learner toward God, truthful conduct, and faithful response; they do not supply a formula for controlling an outcome.
