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 best moments on earth are those during which we meditate upon heavenly things in general, when we recognize or defend the truth, that heavenly dweller and denizen. Only then do we truly live. Therefore, the essential interests of the soul require that we should oftener rise above the earth, upwards to heaven, where is our true life, our true country, which shall have no end.
John of KronstadtShould thoughts of self-praise, of self-satisfaction, occur to you, say: 'I myself am nothing; all that is good in me is accomplished by the grace of God.' What hast thou that thou didst not receive?' (I Cor. 4:7). 'Without Me ye can do nothing' (John 15:5).
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 KronstadtA 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)
