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.
