Fasting
to abstain from food
Stated simply, biblical fasting is refraining from food for a spiritual purpose.
The people went to the temple, obeyed God’s laws, fasted, and appeared eager to seek the Lord; but their worship was only an outward show. Their hearts were far from God (1:10–15; 29:13; Matt. 15:8–9). When we worship because it is the popular thing to do, not because it is the right thing to do, then our worship becomes hypocritical
Dr. Oda H. F. Birchinger, who supervised more than seventy thousand fasts, stated, “Fasting is a royal road to healing, for anyone who agrees to take it, for recovery and regeneration of the body, mind, and spirit.” He went on to say, “Fasting can heal and help rheumatism in the joints and muscles, diseases of the heart, circulation, blood vessels, stress-related exhaustion, skin diseases—including pimples and complexion problems, irregular menstrual cycles and hot flashes, disease of respiratory organs, allergies such as hay fever and other eye diseases.”
