A man becomes spiritual insofar as he lives a spiritual life. He begins to see God in all things, to see His power and might in every manifestation. Always and everywhere he sees himself abiding in God and dependent on God for all things. But insofar as a man lives a bodily life, so much he does he do bodily things; He doesn't see God in anything, even in the the most wondrous manifestations of His Divine power. In all things he sees body, material, everywhere and always - "God is not before his eyes." (Ps. 35:2)
John of KronstadtIt is necessary to rouse the heart to pray, otherwise it will become quite dry. The attributes of prayer must be: love of God, sincerity, and simplicity.
John of KronstadtWhen you are praying alone, and your spirit is dejected, and you are wearied and oppressed by your loneliness, remember then, as always, that God the Trinity looks upon you with eyes brighter than the sun; also all the angels, your own Guardian Angel, and all the Saints of God.
John of KronstadtIf you see the fury and hear the howling of the tempest, or read of shipwrecks, think of the storm of human passions causing daily groans and disturbance in the hearts of men, wrecking the spiritual ship of the soul or the ship of human society; and pray fervently to the Lord that He may subdue the tempest of sins, as He once subdued the tempest at sea by His word, and that He may root our passions from our hearts, and re-establish in them unceasing tranquility.
John of KronstadtWe must by every means humble our hearts and subdue our proud intellect, lest we should be like the contemporaries of the prophets, who looked on them only as sweet-voiced singers, and nothing more; they did not wish to fulfill their commands, they even despised, persecuted, beat and killed them; lest we should be like those, by whom 'no prophet is accepted in his own country' (Lk. 4:24).
