The most abominable enemy endeavours to destroy love by love itself: love for God and our neighbour—by love for the world, for its fleeting blessings and its corrupt, impious habits, by carnal love, by the love of riches, of honours, of pleasure, of various amusements. Therefore let us extinguish every love for this world in ourselves, and let us kindle in ourselves, by self-denial, love for God and our neighbor. Every beauty in this world (personal beauty) is only a faint, insignificant shadow of the uncreated beauty, of the unspeakable goodness of God’s face; every earthly enjoyment is nothing in comparison to future delights. I pray, Lord, that the faith of Christ may penetrate into the depths of my heart, that Christ’s Gospel may penetrate all my thoughts, feelings, words, and deeds, into all my bones and my brains, and not me only, but all men, as the universal truth, the highest wisdom, and the life eternal. “And this is life eternal, that they might know Thee, the only true God, and Jesus Christ, Whom Thou hast sent” [Jn 17.3].
St John of Kronstadt My Life in Christ, 335
