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 favors 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 favor and love for you; a favor so great that it is inconceivable how the great Lord of hosts could grant such favors to our nothingness and worthlessness.

St. Nicodemus of life Holy Mountain

Until a man’s earthly life finishes its course, up to the very departure of the soul from the body, the struggle between sin and righteousness continues within him. However, high a spiritual and moral state one might achieve, a gradual or even headlong and deep fall into the abyss of sin is always possible. Therefore, communion of the holy Body and Blood of Christ, which strengthens our contact with Him and refreshes us with the living streams of the grace of the Holy Spirit flowing through the Body of the Church, is necessary for everyone.

St. John of Shanghai and San Francisco

When God revealed himself, he united himself with our mortal nature in order to deify humanity through this close relation with deity. Since this is so, through his flesh, constituted by bread and wine, he implants himself in all believers.

St. Gregory of Nyssa

If the Lord were not long-suffering, if He were not the Lover of men, would He have borne with our great offences? Would He have been incarnate? Would He have suffered and died for you? Would He have given you His most pure Body and Blood, upon which even the angels look with fear and trembling? Would He have saved you from sin and spiritual death so many innumerable times?

St. John of Kronstadt
