Why Fast?

Fasting is considered one of the many spiritual disciplines. Through
the sacrifice of abstaining from food, one becomes more mindful of
God.

It was interesting to learn that Jesus didn't say to the disciples
'if' you fast...but 'when' you fast...implying that He expected the
disciples to fast.

"Fasting is designed to make prayer mount up as on Eagles wings... it
may be expected to drive back the oppressing powers of darkness and
loosing their hold on the prayer objective. It is calculated to give
an edge to man's intercessions and power to his petitions. Heaven is
ready to bend its ear to listen when someone prays with
fasting."-Arthur Wallis

"It is of supreme importance that you approach the spiritual exercise
bearing in mind these
principles and questions:
1. Am I confident that this desire to fast is God-given?
2. Are my motives right?
3. What are my spiritual objectives in this fast? Intercession? What
special burdens? Divine intervention, guidance, blessing?
4. Am I determined above all else to minister to the Lord in this fast?"

Finally also note:
"Beware of talking about your fast, either how long you fasted or of
experiences you may have been granted during it, "that your fasting
may be in secret," as Christ commanded."
