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 KronstadtHow do we receive the highest mystery of Divine love to us ? the mystery of the Christian faith? With our mind, heart and life; with our free will? Are all the three powers of our souls penetrated by holy faith, as were the souls of the saints? The kingdom of heaven 'is like leaven, which a woman took and hid in three measures of meal till the whole was leavened' (Lk. 13:21). The three measures are the three powers of the soul.
John of KronstadtHow will it be with us in the future life, when everything that has gratified us in this world: riches, honors, food and drink, dress, beautifully furnished dwellings, and all attractive objects-how will it be, I say, when all these things leave us-when they will all seem to us a dream, and when works of faith and virtue, of abstinence, purity, meekness, humility, mercy, patience, obedience, and others will be required of us?
John of KronstadtBesides loving each other, we must bear with each other and pardon ? 'forgive them that trespass against us' ? in order that our heavenly Father may 'forgive us our trespasses' (Mt. 6:14). Thus, with all your soul honor and love in every man the image of God, not regarding his sins, for God alone is Holy and without sin; and see how He loves us, how much He has created and still creates for us, punishing us mercifully and forgiving us bounteously and graciously. Honor the man also, in spite of his sins, for he can always amend.
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).
