From St. John of Kronstadt’s “My Life in Christ”
When praying, endeavour by every means to feel in your heart the truth and the power of the words of the prayer; feed yourself upon them as upon an imperishable food; water your heart with them as with a dew; and warm yourself by them as by means of a beneficial fire.
The Lord is everything to me: He is the strength of my heart and the light of my intellect. He inclines my heart to everything good; He strengthens it; He also gives me good thoughts; He is my rest and my joy; He is my faith, hope and love; He is my food and drink, my raiment, my dwelling place. .As a mother is everything to her infant—its mind, will, sight, hearing, taste, smelling and feeling, as well as its food and drink, its clothing, hands and feet—so, likewise, the Lord is everything to me, when I yield myself wholly unto Him. But, alas! when I fall away from the Lord, then the Devil enters into me, and if I did not turn my heart’s gaze towards the Lord, did I not, amidst the enemy’s oppression, call upon the Lord for help, then the Devil would have been, as he sometimes is, very evil to me: malice, despondency, perfect feebleness towards everything good, despair, hatred, envy, avarice, blasphemous, wicked and impure thoughts, contempt for everything—in short, he would have been, and sometimes is, my intellect, my will, sight, hearing, taste, smell, feeling, my hands and feet. Therefore, put your trust in the Lord. He is that which is, infinite in holiness, omnipotence, grace, mercy, bountifulness, and wisdom.
