When 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 KronstadtIt would seem, after this, that even when living upon earth we must live as if in the heavenly kingdom, dwelling there in anticipation by hope. But in reality, for the greater part, the contrary is the case. Men cling with their whole being to the earth and everything earthly.
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 KronstadtWhen you are in the temple, remember that you are in the living presence of the Lord God, that you stand before His face, before His eyes, in the living presence of the Mother of God, of the holy angels, and of the first-born of the Church - that is, our forefathers, the prophets, Apostles, hierarchs, martyrs, reverend Fathers, the righteous, and all the saints. Always have the remembrance and consciousness of this when you are in the temple, and stand with devotion, taking part willingly and with all your heart in the Divine service.
John of Kronstadt'If he trespass against you seven times in a day, and seven times in a day turn again to you, saying, I repent; you shall forgive him' (Lk. 17:4). As the Searcher of hearts, the Lord knows that men are liable to very frequent trespass, and that, having fallen, they often rise up again; therefore He has given us the commandment to frequently forgive trespasses, and He Himself is the first to fulfill His holy word. As soon as you say from your whole heart, 'I repent,' you will be immediately forgiven.
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.
