In prayer and in every work of your life avoid suspicious ness, doubt and diabolical imaginations. Let your spiritual eye be single, in order that the whole body of your prayer, of your works and of your life may be light.
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 KronstadtHe who is accustomed to give account of his life at confession here will not fear to give an answer at the terrible judgment-seat of Christ. It is for this purpose that the mild tribunal of penitence was here initiated, in order that we, being cleansed and amended through penitence here below, may give an answer without shame at the terrible judgment-seat of Christ.
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 KronstadtIf you are fond of dressing elegantly, or when you put on your clothes, think of the incorruptible garment of righteousness in which our souls should be arrayed, or of Jesus Christ Who is our spiritual raiment, as it is said: 'For as many of you as have been baptized into Christ, have put on Christ' (Gal. 3:27).
John of KronstadtAvoid duplicity, that is, do not let your heart be divided between attachment to God and attachment to earthly things, 'You cannot serve God and mammon' (Mt. 6:24); cling to God alone, put your trust in Him alone; for the Devil, by inciting us to duplicity, seeks himself to gain possession of our heart, which is single and indivisible.
