A fast is not a hunger strike. Fasting submits to God’s commands. A hunger strike makes God submit to our demands.
Fasting
Dallas Willard
Solitude well practiced will break the power of busyness, haste, isolation, and loneliness. You will see that the world is not on your shoulders after all. You will find yourself, and God will find you in new ways. Silence also brings Sabbath to you. It completes solitude, for without it you cannot be alone. Far from being a mere absence, silence allows the reality of God to stand in the midst of your life. God does not ordinarily compete for our attention. In silence, we come to attend. Lastly, fasting is done that we may consciously experience the direct sustenance of God to our body and our whole person.]
Amanda Jobs
It is not just about giving up our favorite food but it’s about going further and giving up things like hatred and unforgiveness. You need to clean your heart and prepare yourself for purity.
Anthony M. Coniaris
Man hungers for material food but he also has a hunger for something far greater. This is why Jesus said, “Man shall not live by bread alone”. Greater than the hunger for food in man is the hunger for God which manifests itself basically in the hunger for security, for love, peace, joy, meaning, and life. All these hungers find their complete and permanent satisfaction in Christ.
John Piper
Do you have a hunger for God? If we don’t feel strong desires for the manifestation of the glory of God, it is not because we have drunk deeply and are satisfied. It is because we have nibbled so long at the table of the world. Our soul is stuffed with small things, and there is no room for the great. If we are full of what the world offers, then perhaps a fast might express, or even increase, our soul’s appetite for God. Between the dangers of self-denial and self-indulgence is the path of pleasant pain called fasting.
Isaac of Syria
When the devil, the foe and the tyrant, sees a man bearing this weapon [fasting], he is straight-away frightened and he recollects and considers that defeat which he suffered in the wilderness at the hands of the Saviour; at once his strength is shattered and the very sight of this weapon, given us by our Commander-in-chief, burns him.
Albert Haase
Fasting can be a painful admission that I am not free, that my life is enslaved, obsessed or addicted to external things such as food, drink, codependent relationships, sex, television, privacy and the like.
Arthur Wallis
Fasting is important, more important perhaps, than many of us have supposed,…when exercised with a pure heart and a right motive, fasting may provide us with a key to unlock doors where other keys have failed; a window opening up new horizons in the unseen world; a spiritual weapon of God’s provision, mighty, to the pulling down of strongholds.
Martyn Lloyd-Jones
Fasting, if we conceive of it truly, must not… be confined to the question of food and drink; fasting should really be made to include abstinence from anything which is legitimate in and of itself for the sake of some special spiritual purpose. There are many bodily functions which are right and normal and perfectly legitimate, but which for special peculiar reasons in certain circumstances should be controlled. That is fasting.
John Chrysostom
No act of virtue can be great if it is not followed by advantage for others. So, no matter how much time you spend fasting, no matter how much you sleep on a hard floor and eat ashes and sigh continually, if you do no good to others, you do nothing great.
