Have you learned to see God and represent Him to yourself--as the omnipresent Wisdom, as the living, acting Word, as the vivifying Holy Spirit? The Holy Scripture is the domain of Wisdom, Word and Spirit, of God in the Trinity: in it He clearly manifests Himself: "The Words that I speak unto you, they are spirit, and they are life,"  said the Lord. The writings of the Holy Fathers are again the expression of the Mind, Word and Spirit of the Holy Trinity, in which the spirit of the higher class (spiritually speaking) of mankind has largely participated; the writings of ordinary worldly men are the expression of the fallen spirit of men, with all their sinful attachments, habits and passions. In the Holy Scriptures we see God face to face, and ourselves as we are. Man, know thy self through them, and walk always as in the presence of God.
In the temple, in its arrangements and parts, in the icons, in the Divine service, with the reading of the Holy Scriptures, the singing, the rites, the entire Old Testament, New Testament, and Church history, the whole Divine ordering of the salvation of mankind is emblematically traced, as upon a chart, in figures and in general outlines. Grand is the spectacle of the Divine service of our Orthodox Church for those who understand it, who penetrate into its essence, its spirit, its signification, its sense!
The Church, through the temple and Divine service, acts upon the entire man, educates him wholly; acts upon his sight, hearing, smelling, feeling, taste, imagination, mind, and will, by the splendour of the icons and of the whole temple, by the ringing of bells, by the singing of the choir, by the fragrance of the incense, the kissing of the Gospel, of the cross and the holy icons, by the prosphoras, the singing, and sweet sound of the readings of the Scriptures.
The thoughts of a man have the most powerful influence upon the state and inclinations of his heart and actions; therefore, in order that the heart may be pure, good, tranquil, and that the inclinations of the will may be also good and pious, it is necessary to cleanse our thoughts by means of prayer, by reading the Holy Scriptures and the writings of the Holy Fathers, as well as by meditations on the perishableness, transitoriness, and complete disappearance of earthly delights.
St John of Kronstadt
