A man becomes spiritual insofar as he lives a spiritual life. He begins to see God in all things, to see His power and might in every manifestation. Always and everywhere he sees himself abiding in God and dependent on God for all things. But insofar as a man lives a bodily life, so much he does he do bodily things; He doesn't see God in anything, even in the the most wondrous manifestations of His Divine power. In all things he sees body, material, everywhere and always - "God is not before his eyes." (Ps. 35:2)
John of KronstadtDo not be irritated either with those who sin or those who offend; do not have a passion for noticing every sin in your neighbour, and for judging him, as we are in the habit of doing. Everyone shall give an answer to God for himself. Everyone has a conscience; everyone hears God's Word, and knows God's Will either from books or from conversation with other people. Especially do not look with evil intention upon the sins of your elders, which do not regard you; "to his own master he standeth or falleth." Correct your own sins, amend your own life.
John of KronstadtDo not lose your temper with those who sin. Do not have a passion for noticing every sin in your neighbor and judging it, as we usually do. Everyone will give an answer for himself before God. Especially, do not look with evil intention on the sins of those older than you, with whom you have no business. But correct your own sins, your own heart.
John of KronstadtThe accursed one does not allow the eye of the heart to see the Lord or His saints. He darkens our heart in every way. He scatters faith, oppressing, burning and darkening us inwardly. We must look upon all such actions as illusions and falsehood, and break through this imaginary wall to the Lord, or to His Holy Mother, or His saints. As soon as you break through this wall you will be immediately saved. 'Your faith has made you whole' (Mt. 9:22).
John of KronstadtWhen you see your body wasted away through sickness, do not murmur against God, but say: 'The Lord gave, and the Lord has taken away; blessed be the name of the Lord' (Job 1:21). You are accustomed to look upon your body as upon your own inalienable property, but that is quite wrong, because your body is God's edifice.
John of KronstadtChrist is our hope, our cleansing and santification, our resurrection, life and repose. He alone is what we all need, and therefore, the Orthodox Church constantaly pronounces these words aloud so that we may hear them during Holy Services of the Church, and be constantly renewed. For we are inclined to forget the only thing we need. With death all will be taken from us, all earthly goods, riches, beauty of body and raiment, spacious dwellings, etc., but the virtue of the soul, that incorruptible raiment, shall remain with us eternally.
John of Kronstadt
