Do not despise any man, however poor he may be; but behave with full respect and kindness to every well-intentioned man, especially to the poor, as to our members worthy of compassion - or, rather, to members of Christ - otherwise you will cruelly wound your soul.
John of Kronstadt...when seeking material light, remember the spiritual light which is indispensable for the soul, and without which it remains in the darkness of the passions, in the darkness of spiritual death. 'I am come as a light into the world,' says the Lord, 'that whosoever believeth on Me, should not abide in darkness' (Jn. 12:46).
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 KronstadtHe who is insolent towards men is insolent towards God... Respect in man the grand, inestimable image of God and be forbearing towards the faults and errors of fallen man, so that God may be forbearing towards your own.
John of KronstadtDo not be despondent when fighting against the incorporeal enemy, but even in the midst of your afflictions and oppression praise the Lord, Who has found you worthy to suffer for Him, by struggling against the subtlety of the serpent, and to be wounded for Him at every hour; for had you not lived piously, and endeavored to become united to God, the enemy would not have attacked and tormented you.
John of KronstadtAvoid 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.
