Holman Bible Dictionary
Fasting is the laying aside of food for a period of time when the believer is seeking to know God in a deeper experience. It is to be done as an act before God in the privacy of one's own pursuit of God (Exodus 34:28; 1 Samuel 7:6; 1 Kings 19:8; Matthew 6:17 ).
Fasting is to be done with the object of seeking to know God in a deeper experience (Isaiah 58:1; Zechariah 7:5 ). Fasting relates to a time of confession (Psalm 69:10 ). Fasting can be a time of seeking a deeper prayer experience and drawing near to God in prevailing prayer (Ezra 8:23; Joel 2:12 ). The early church often fasted in seeking God's will for leadership in the local church (Acts 13:2 ). When the early church wanted to know the mind of God, there was a time of prayer and fasting.
