Without temptations, it is not possible to learn the wisdom of the Spirit. It is not possible that Divine love be strengthened in your soul. Before temptations, a man prays to God as a stranger. When temptations are allowed to come by the love of God, and he does not give in to them, then he stands before God as a sincere friend. For in fulfilling the will of God, he has made war on the enemy of God and conquered him.
Isaac of NinevehThere is love like a small lamp, which goes out when the oil is consumed; or like a stream which dries up when it doesn't rain. But there is a love that is like a mighty spring gushing up out of the earth; it keeps flowing forever, and is inexhaustible.
Isaac of NinevehBe dead in life, and you will not live in death. Let your soul die strenuously, and not live in weakness. Not only those who suffer death for the sake of faith in Christ are martyrs; but also those who die because of their observance of His commandments.
Isaac of NinevehIf you practice an excellent virtue without perceiving the taste of its aid, do not marvel; for until a man becomes humble, he will not receive a reward for his labor. Recompense is given, not for labor, but for humility.
