When despondency seizes us, let us not give in to it. Rather, fortified and protected by the light of faith, let us with great courage say to the spirit of evil: 'What are you to us, you who are cut off from God, a fugitive for Heaven, and a slave of evil? You dare not do anything to us: Christ, the Son of God, has dominion over us and over all. Leave us, you thing of bane. We are made steadfast by the uprightness of His Cross. Serpent, we trample on your head.'
Unless curbed by the fear of God that accompanies the practice of the virtues, spiritual knowledge leads to vanity; for it encourages the person puffed up by it to regard as his own what has merely been lent to him, and to use his borrowed intelligence to win praise for himself. But when his practice of the virtues increases concomitantly with his longing for God, and he does not arrogate to himself more spiritual knowledge than is needed for the task in hand, then he is made humble, reduced to himself by principles which are beyond his capacity.
Have confidence in the compassion of our Creator. Reflect well on what you are now doing, and keep before you the things you have done. Lift up your eyes to the overflowing compassion of heaven, and while He waits for you, draw near in tears to our merciful Judge. Having before your mind that He is a Just Judge, do not take your sins lightly; and having also in mind that He is compassionate, do not despair. The God-Man gives man confidence before God.
Ever let mercy outweigh all else in you. Let our compassion be a mirror where we may see in ourselves that likeness and that true image which belong to the Divine nature and Divine essence. A heart hard and unmerciful will never be pure.
If you speak of pagan abuses, these abuses do not make our veneration of images loathsome. Blame the pagans, who made images into gods! Just because the pagans used them in a foul way, that is no reason to object to our pious practice. Sorcerers and magicians use incantations and the Church prays over catechumens; the former conjure up demons while the Church calls upon God to exorcise the demons. Pagans make images of demons which they address as gods, but we make images of God incarnate, and of His servants and friends, and with them we drive away the demonic hosts... If the Scripture says, The idols of the nations are silver and gold, the work of men's hands (Ps. 135:15), it is not forbidden to bow before inanimate things, or the handiwork of men, but only before those images which are the devil's work.
An icon is a symbol of the invisible. It depicts not only the outward, visible countenance of the Lord and His saints, but also their inner likeness, their sanctity.
Even if we have thousands of acts of great virtue to our credit, our confidence in being heard must be based on God's mercy and His love for men. Even if we stand at the very summit of virtue, it is by mercy that we shall be saved.
