In order that you may move your will more easily to this one desire, in everything—to please (God and to work for His glory alone—remind yourself’ often, that He has granted you many favours in the past and has shown you His love. He has created you out of nothing in His own likeness and image, and has made all other creatures your servants; He has delivered you from your slavery to the devil, sending down not one of the angels but His Only-begotten Son to redeem you, not at the price of corruptible gold and silver, but by His priceless blood and His most painful and degrading death. Having done all this He protects you, every hour and every moment, from your enemies; He fights your battles by His divine grace; in His immaculate Mysteries He prepares the Body and Blood of His beloved Son for your food and protection. All this is a sign of God’s great favour and love for you; a favour so great that it is inconceivable how the great Lord of hosts could grant such favours to our nothingness and worthlessness.
+ From Unseen Warfare, St. Theophan the Recluse and St. Nicodemus of the Holy Mountain
“What does our Christ instruct us to do? Meditate on our sins, on death, on hell, on paradise, and on our soul, which is more precious than the entire world. We are to eat and drink moderately, similarly, to clothe ourselves moderately, and to use the remaining time for our soul-to make it a bride for our Christ. And then we can call ourselves human beings and earthly angels. But if we concern ourselves with what we shall eat and what we shall drink, how we shall commit sin, how to dress up this stinking body which tomorrow will be eaten by worms, and do not concern ourselves about our soul which is eternal, then we can’t be called human beings, but animals. So make your body a servant of the soul, and then you can call Yourselves human beings.”
