How to fast according to the Bible?

Biblical fasting is abstaining from food for a spiritual purpose. It is not a way to manipulate God, but a way to humble oneself, intensify prayer, and seek God's will. Jesus assumed his followers would fast, giving instructions on how to do it sincerely.

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.

Matthew 6:16 (NIV)

Understanding Matthew 6:16

Fasting—abstaining from food for a spiritual purpose—is a discipline practiced throughout the Bible by figures like Moses, David, Esther, Daniel, and Jesus himself. It is often misunderstood as a hunger strike to force God's hand, but its true purpose is humility and focus.

Jesus gave clear instructions in Matthew 6:16-18: 'When you fast, do not look somber as the hypocrites do... put oil on your head and wash your face.' Biblical fasting is to be done in secret, not for public approval.

There are different types of fasts in Scripture: a complete fast (no food or water, usually short like Acts 9:9), a normal fast (water only), and a partial fast (restricting certain foods, like Daniel 10:3).

The goal of fasting is to disconnect from the physical to connect with the spiritual. It reveals our dependence on God ('man does not live on bread alone'), exposes our inner compulsions, and creates space for intensified prayer. It is appropriate for times of repentance, seeking guidance, or intercession for others.
