Avoid duplicity, that is, do not let your heart be divided between attachment to God and attachment to earthly things, 'You cannot serve God and mammon' (Mt. 6:24); cling to God alone, put your trust in Him alone; for the Devil, by inciting us to duplicity, seeks himself to gain possession of our heart, which is single and indivisible.
John of KronstadtWhen you say a prayer, He (The Holy Spirit) is in every word of it, and like a Holy Fire, penetrates each word.
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).
John of KronstadtThe Lord called Himself and is the 'good Shepherd' (Jn. 10:11). If you believe in His guidance, then you will understand by your heart that as a zealous shepherd when feeding his flock does not allow the sheep to disperse, but gathers them together, so also the Lord pastures our souls, not allowing them to wander in falsehood and sins, but gathering them on the path of virtue, and not allowing the mental wolf to steal and scatter them.
John of KronstadtThe Saviour and the Comforter, two Persons of the Godhead: the One ever saves from sins, and the Other comforts him who is saved. Their very names are taken from their deeds, and are always actually justified. He comforts! The Holy Spirit comforts the believing soul, as a mother comforts her child.
John of KronstadtChrist wishes to raise men up to heaven, and has given them all the means to attain this; whilst the Devil, who himself for his pride was cast down from heaven into the dominions of the air, wishes by every means to attach men to earthly,- sensual, transitory things, and, in order to attain this end, he employs the most powerful, most prodigious means.
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 Kronstadt
