Fasting, however, isn’t a way of persuading God to do something in your behalf. Fasting doesn’t change God; it changes you; it positions you spiritually so you can receive from Him. For instance, the instruction from the Lord to the apostles that Barnabas and Saul (who later became Paul) should be consecrated to the work of the ministry came as the apostles fasted and prayed: “As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them” (Acts 13:2).
