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 KronstadtGod is nearer to us than any man at every time. He is nearer to me than my raiment, nearer than the air or light, nearer than my wife, father, mother, daughter, son, or friend. I live in Him, soul and body. I breathe in Him, think in Him, feel, consider, intend, speak, undertake, work in Him.
John of Kronstadt
