Fasting is beneficial
Many
 Christians, unaware of the great value of fasting, either keep the fast
 with difficulty or reject it altogether. We should not be afraid to 
fast but embrace it with joy. There is nothing for us to fear; rather, 
fasting is fearful for the demons. When she is brought before them, they
 are overcome with fear, they freeze and become paralyzed, and they are 
bound with invisible chains—especially when she
 is accompanied by her inseparable companion, prayer. This is why Christ
 said, “this generation [of demons] does not come out other than with 
prayer and fasting” (Mt. 17:21).
Since
 fasting drives the enemies of our salvation far away and is so 
frightful to them who oppress us, we should love her dearly, not be 
afraid of her. If there is something for us to fear, it is overeating 
and drunkenness. Because they handcuff us and lead us captive to the 
cruel passions, whereas fasting frees us from the torturous passions and
 grants spiritual freedom to us. Since fasting fights against our 
enemies, frees us from slavery, and restores our freedom, what other 
reasons do we need in order
to embrace her?
I
 remind you of the two chief prophets of the Old Testament, Moses and 
Elijah. They had great boldness before God on account of their other 
virtues; yet, when they wanted to speak with Him, they fled to fasting, 
which in turn brought them closer to the Lord (vid. Ex. 24:18; 3 Kg 
19:8).  
Even
 long before them, at the very beginning of creation when God made man, 
He immediately entrusted him into the hands of fasting, in order for 
her, like a compassionate mother and excellent teacher, to secure his 
salvation. The declaration “you may eat food from every tree in the 
garden; but from the tree of the knowledge of good and evil you may not 
eat” (Gen. 2:16-17) was nothing other than a commandment to fast. If 
fasting was necessary in Paradise, it is much more essential [for us] 
out of paradise. If it served as useful medication prior to the wound, 
it is much more useful now that we have become wounded. If it was an 
indispensable weapon before war broke out with the passions and the 
demons, it is much more necessary now that the war has been initiated. 
Fasting
 made God recall His decision to destroy the Ninevites. Jonah went to 
Nineveh and conveyed the divine verdict to its citizens: “Three more 
days and Nineveh shall be destroyed” (Jon. 3:4). When the people heard 
this, they did not doubt or remain indifferent. Rather, everyone quickly
 fled to fasting—men,
 women, masters, slaves, rulers, residents, children, and the elderly. 
Fasting was even imposed upon the irrational animals. Simultaneously, 
everyone throughout the city mourned, prayed, and repented. Do you see 
why I said earlier that we should be afraid of overeating and 
drunkenness? These two things almost destroyed Nineveh, whereas fasting 
saved the city from certain destruction.
The
 prophet Daniel entered into the lions’ den along with fasting and came 
out unharmed, as if he had been thrown into a sheep’s pen (Dan. 
6:16-23). 
The three youths entered into the furnace with fasting, and this is 
why they exited from the fire with their bodies intact and shinning 
(Dan. 3:19-27). If that was a real fire, why didn’t it do what fire 
normally does? If those were real bodies, why were they not burnt like 
normal bodies? Why? Ask fasting. She will give you the answer; she will 
solve the puzzle for  you.  It is truly an enigma how human bodies 
wrestled with and prevailed over fire. Do you see the extraordinary 
battle? Do you see the even more wondrous victory? Marvel at fasting and
 receive her with open arms.  
Because
 when she is capable of rescuing people from fire, guarding others from 
lions, distancing the demons, overruling God’s decision, subduing the 
crazed passions, restoring our freedom, and granting peace to our soul, 
when she holds so many goods in her hands, isn’t it foolish for us to 
avoid and be afraid of fasting?
