Put not your trust in princes,
in a son of man, in whom there is no salvation.
When his breath departs, he returns to the earth;
on that very day his plans perish.
Blessed is he whose help is the God of Jacob,
whose hope is in the LORD his God,
who made heaven and earth,
the sea, and all that is in them,
who keeps faith forever;
who executes justice for the oppressed,
who gives food to the hungry.
That which a man loves, to which he turns, that he will find. If he loves earthly things, he will find earthly things, and these earthly things will abide in his heart, will communicate their earthliness to him and will find him; if he loves heavenly things, he will find heavenly things, and they will abide in his heart and give him life. We must not set our hearts upon anything earthly, for the spirit of evil is incorporated in all earthly things when we use them immoderately and in excess, this spirit having become earthly by excessive opposition to God.
When God is present in all a man’s thoughts, desires, intentions, words, and works, then it means that the kingdom of God has come to him; then he sees God in everything—in the world of thought, in the world of action, and in the material world; then the omnipresence of God is most clearly revealed to him, and a genuine fear of God dwells in his heart: he seeks every moment to please God, and fears every moment lest he may sin against God, present at his right hand. “Thy kingdom come!“
Examine yourself oftener; where the eyes of your heart are looking. Are they turned towards God and the life to come, towards the most peaceful, blessed, resplendent, heavenly, holy powers dwelling in heaven? Or are they turned towards the world, towards earthly blessings; to food, drink, dress, abode, to sinful vain men and their occupations? O that the eyes of our heart were always fixed upon God! But it is only in need or misfortune that we turn our eyes to the Lord, whilst in the time of prosperity our eyes are turned towards the world and its vain works. But what, you would ask, will this looking to God bring me? It will bring the deepest peace and tranquillity to your heart, light to your mind, holy zeal to your will, and deliverance from the snares of the enemy.
(St. John of Kronstadt, My Life in Christ, pp. 76-77)
Then Jesus said to them, “Render therefore to Caesar the things that are Caesar’s, and to God the things that are God’s.” When they heard it, they marveled; and they left him and went away. (Matthew 22:21-22)
