So we fasted and entreated our God for this, and He answered our prayer. (Ezra 8:23)
Oswald Chambers said in his writings, If Ye Shall Ask, "Our Lord in His teachings always made prayer, not preparation for work, but the work." For example, Jesus did not pray in the garden of Gethsemane for strength for the battle of Calvary, Gethsemane was the battle. Calvary was the victory. Prayer and fasting go hand in hand. Nevertheless, not all prayer requires fasting, but all life requires prayer. Fasting is to be called, not necessarily chosen. There are certain situations that necessitate fasting: repentance, humility, deliverance, and direction. Let us pray without ceasing, but let us fast with a leading. Prayer for the believer should be as much a part of life as eating and fasting as special as abstaining from eating. We do not fast to get God's attention. We fast to get our attention on the things of God. Jesus clearly taught that there is a time to fast and pray a way to fast and pray.
