Fasting and prayer are talked about throughout the Bible for many reasons such as worshiping God, to express grief, to prepare for ministry, to seek God's wisdom, and more. Fasting is abstaining from all or some kinds of food or drink, especially as a religious observance. A number of studies have suggested intermittent fasting has numerous health benefits, including weight loss, lower blood pressure and reduced cholesterol.
Dr. Bill Bright, in his guide Why You Should Fast, listed the following reasons for seeking God through self-denial.
•Fasting was an expected discipline in both the Old and New Testament eras.
•Fasting and prayer can restore the loss of the “first love” for your Lord and result in a more intimate relationship with Christ.
•Fasting is a biblical way to truly humble yourself in the sight of God.
•It enables the Holy Spirit to reveal your true spiritual condition, resulting in brokenness, repentance, and a transformed life.
•Fasting will encourage the Holy Spirit to quicken the Word of God in your heart and His truth will become more meaningful to you.
•Fasting can transform your prayer life into a richer and more personal experience.
•Fasting can result in a dynamic personal revival in your own life and make you a channel of revival to others.
