1. 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."
Jesus assumes His followers will fast ("when you fast," not "if"), making fasting normative for believers. He contrasts hypocritical fasting for human approval with sincere fasting for God alone. The Pharisees fasted twice weekly (Luke 18:12) and made their fasting conspicuous through ashes, unwashed faces, and mournful expressions. Jesus commands the opposite: normal appearance while fasting, keeping the discipline between the believer and God. The promise of the Father's reward emphasizes that genuine fasting focuses on relationship with God, not religious performance. This teaching revolutionized fasting from external ritual to internal devotion (BibleHub Commentaries).

2. Joel 2:12

""Even now," declares the Lord, "return to me with all your heart, with fasting and weeping and mourning.""
Joel calls for corporate fasting during national crisis, linking fasting with genuine repentance. "Even now" offers hope despite judgment's nearness. The triad of fasting, weeping, and mourning represents complete contrition - fasting (physical humility), weeping (emotional brokenness), and mourning (spiritual grief over sin). "With all your heart" demands total commitment, not mere external compliance. This verse establishes fasting as appropriate response to personal and corporate sin, demonstrating sincerity in seeking God's mercy. The next verse clarifies: "rend your heart and not your garments," prioritizing internal transformation over external ritual (BibleHub Commentaries).

3. 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?"
God rejects religious fasting divorced from social justice, defining true fasting as active compassion. Israel fasted religiously while oppressing workers and ignoring the needy. God's chosen fast involves six actions: breaking injustice, freeing the oppressed, feeding the hungry, sheltering the homeless, clothing the naked, and helping family. This isn't replacing spiritual fasting with social action but integrating them - genuine fasting produces compassionate action. The passage promises that such fasting brings healing, righteousness, and answered prayer (verses 8-9). Isaiah establishes that authentic fasting transforms both the one fasting and their community (BibleHub Commentaries).

4. 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."
The Antioch church's practice of corporate fasting and worship created the environment for receiving divine direction that launched Paul's missionary journeys. "Worshiping and fasting" (Greek: leitourgeo and nesteuo) shows fasting integrated with worship, not separate from it. The Holy Spirit's direct communication during fasting demonstrates heightened spiritual receptivity. They fasted twice - first when receiving the word, then when commissioning the missionaries - showing fasting's role in both receiving and confirming God's will. This passage establishes fasting as essential for major ministry decisions and spiritual breakthroughs in the early church (BibleHub Commentaries).

5. Matthew 17:21

"[This verse is not included in many modern translations]"
Though textually disputed, this verse appears in many manuscripts following Jesus' exorcism of a demon the disciples couldn't cast out. "This kind" suggests certain spiritual battles require intensified spiritual disciplines. The coupling of prayer with fasting indicates fasting amplifies prayer's effectiveness in spiritual warfare. Whether original or early addition, the church historically understood some spiritual victories require the heightened focus and dependence on God that fasting provides. The verse teaches that fasting isn't magical but deepens reliance on God's power rather than human ability (BibleHub Commentaries).

6. 2 Chronicles 20:3-4

"Alarmed, Jehoshaphat resolved to inquire of the Lord, and he proclaimed a fast for all Judah. The people of Judah came together to seek help from the Lord; indeed, they came from every town in Judah to seek him."
Facing overwhelming military threat from Moab and Ammon, Jehoshaphat's first response was proclaiming a national fast. His fear drove him to "seek the Lord" (Hebrew: darash - to search out, inquire). The fast unified the nation in desperate dependence on God. The result was supernatural victory without fighting - God caused the enemies to destroy each other (verses 22-23). This demonstrates fasting as appropriate response to crisis, unifying God's people in seeking divine intervention. The corporate nature ("all Judah") shows fasting's power in bringing communities together in humble dependence on God (BibleHub Commentaries).

7. Esther 4:16

""Go, gather together all the Jews who are in Susa, and fast for me. Do not eat or drink for three days, night or day. I and my attendants will fast as you do. When this is done, I will go to the king, even though it is against the law. And if I perish, I perish.""
Esther institutes corporate fasting as crisis intervention, calling for a complete three-day fast without food or water (אַל-תֹאכְלו וְאַל-תִשְתּו) among all Jews in Susa before risking her life to approach King Xerxes uninvited. The phrase "night or day" (לַיְלָה וָיוֹם) emphasizes the fast's absolute nature—"an act of complete surrender and dependence on God in the face of a life-threatening crisis." This corporate discipline unified the entire Jewish community facing annihilation under Haman's decree. Esther's strategy demonstrates that "special spiritual battles sometimes require special preparation with prayer and fasting." The fast served multiple purposes: seeking divine favor for an impossible situation (approaching the king unsummoned was punishable by death), fostering "unity among believers as we come together in prayer and focus our hearts on a common purpose," and expressing "both humility and desperation, a plea for divine intervention in a matter of life and death." The Esther Fast represents "Supplication and Humiliation, where Esther and her people fasted and prayed for God's intervention," reminding us that "in times of crisis, it can be easy to take matters into our own hands" but "the story of Queen Esther... serves as a powerful reminder of the importance of supplication and humility in such situations." (Bible Hub Commentaries)

8. Daniel 10:3

"I ate no choice food; no meat or wine touched my lips; and I used no lotions at all until the three weeks were over."
Daniel's three-week partial fast establishes a model of selective dietary restriction for spiritual breakthrough rather than complete food abstinence. The phrase "choice food" (לֶחֶם חֲמֻדוֹת) or "pleasant bread" refers to "bread made of the finest wheat eaten in royal courts," while "meat" (בָשָׂר) and "wine" (יַיִן) represent luxury items. Instead, Daniel ate "coarse, black and grainy bread," demonstrating intentional simplicity. Most scholars agree "choice foods would have included breads and sweets," making Daniel's fast a principled rejection of indulgence while maintaining necessary nutrition. This "partial fast" differs from absolute fasting by "involving limiting certain foods rather than complete abstinence," yet maintains serious spiritual intent. The 21-day duration (שָלֹשִׁים יָמִים) parallels significant biblical time periods for spiritual preparation. Modern applications emphasize that "the intention of the modern-day Daniel Fast is not to duplicate exactly what Daniel did but the spirit in which he did it" since "Daniel's passion for the Lord caused him to hunger and thirst more for spiritual food than for physical food." The key principle remains that "we don't want to become so legalistic that we miss the whole purpose of the fast"—drawing closer to God through disciplined seeking. (Bible Hub Commentaries)
