Do 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 heart is refined, spiritual, and heavenly by nature - guard it; do not overburden it, do not make it earthly, be temperate to the utmost in food and drink, and in general in bodily pleasures. The heart is the temple of God. 'If any man defile the temple of God, him shall God destroy' (I Cor. 3:17).
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 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 KronstadtYour Lord is Love: love Him and in Him all men, as His children in Christ. Your Lord is a fire: do not let your heart be cold, but burn with faith and love. Your Lord is light: do not walk in darkness of mind, without reasoning or understanding, or without faith. Your Lord is a God of mercy and bountifulness: be a source of mercy and bountifulness to your neighbors. If you will be such, you will find salvation yourself with everlasting glory.
John of KronstadtThe Lord, before His Incarnation, let mankind experience all the bitterness of sin, all their powerlessness to eradicate it; and when all longed for a Deliverer, then He appeared, the most wise, all-powerful Physician and Helper. When men hungered and thirsted after righteousness, as it grew weaker, then the everlasting righteousness came.
