📖 Biblical Definition
Biblical fasting is the deliberate, temporary abstinence from food (and sometimes drink) undertaken as a spiritual discipline to humble the soul before God, intensify prayer, and seek divine guidance or intervention. Moses fasted forty days on Sinai (Exodus 34:28). Jesus fasted forty days in the wilderness before His public ministry (Matthew 4:2). Jesus taught His disciples not if but "when you fast" (Matthew 6:16), indicating it is an expected practice. Biblical fasting is not a hunger strike to compel God but a posture of humility that says the soul's need is greater than the body's need.

⚠️ Modern Corruption
Fasting has been secularized into a health trend and stripped of its spiritual purpose.

Modern culture has embraced "intermittent fasting" as a weight loss strategy while the church has largely abandoned fasting as a spiritual discipline. When Christians do fast, it is often treated as a spiritual technique to get what they want from God rather than a posture of humble dependence. The prosperity gospel turns fasting into a transaction: fast long enough and God owes you a breakthrough. Meanwhile, mainstream evangelicalism simply ignores it -- most church members have never fasted in their lives. Jesus said "when you fast," not "if you fast." The early church fasted regularly. The loss of fasting from Christian practice reflects a church that is well-fed, comfortable, and spiritually dull.
Usage
• "Biblical fasting is not a diet plan -- it is the voluntary affliction of the body to sharpen the soul's dependence on God."
• "A church that never fasts has traded the discipline of the apostles for the comfort of the age."
