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 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 KronstadtIf God has given us Himself, if He abides in us and we in Him, according to His own true words, then what will He not give me, what will He spare for me, of what will He deprive me, how can He forsake me? 'The Lord is my shepherd: therefore I lack nothing' (Ps. 23:1).
John of KronstadtEvil and faults are corrected by good, by love, kindness, meekness, humility, and patience.
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.
