When you pray either aloud or to yourself for others ? for instance, for the members of your household or for strangers, even though they may not have asked you to do so ? pray for them with the same ardor and zeal as you would pray for yourself. Remember the commandment of the law: 'You shall love your neighbor as yourself' (Lev. 19:18). Observe this rule upon all occasions.
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 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 KronstadtPrayer is spiritual breathing; when we pray we breathe in the Holy Spirit; praying in the Holy Spirit (Jd. 1:20). Thus, all church prayers are the breathing of the Holy Spirit; as it were spiritual air and also light, spiritual fire, spiritual food and spiritual raiment.
John of KronstadtDo not be despondent when fighting against the incorporeal enemy, but even in the midst of your afflictions and oppression praise the Lord, Who has found you worthy to suffer for Him, by struggling against the subtlety of the serpent, and to be wounded for Him at every hour; for had you not lived piously, and endeavored to become united to God, the enemy would not have attacked and tormented you.
