Biblical fasting is not a religious performance or a diet: it is voluntarily giving up food to seek God with greater intensity. Moses, David, Esther, Daniel, Jesus himself, all fasted at decisive hours. "When you fast," says Jesus (Matthew 6:17): not "if," but "when."
Isaiah 58 reframes the essential: the fast that pleases God detaches from the superfluous and opens the heart, it "releases the bonds of wickedness" and shares bread with the hungry. Fasting without loving is just an empty stomach.

Frequently asked questions about fasting
Is fasting mandatory for a Christian?
It is not a command, but Jesus assumes it ("when you fast," Matthew 6:17) and the church in Acts practiced it at key moments. It is an offered discipline, not a debt to pay.
How do I fast for the first time?
Start small: one meal, then one day, with a clear spiritual goal, replacing mealtime with prayer. Drink water, keep it secret (Matthew 6:16-18), and check with a doctor if you have a health concern.
What is fasting for?
Starving the body to sharpen the spirit: seeking direction (Acts 13:2), supporting intercession (Esther 4:16), breaking spiritual resistance (Mark 9:29), or simply drawing closer to God.
