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 NinevehThe soul that loves God has its rest in God and in God alone. In all the paths that men walk in in the world, they do not attain peace until they draw nigh to hope in God.
Isaac of NinevehThe wisdom of the Holy Spirit is much greater than the wisdom of the entire world. Within the wisdom of the Holy Spirit, silence prevails; the wisdom of the world, however, goes astray into idle talk.
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, at the time when the mind is praying it is distracted by any extraneous thought or worry about anything, then this prayer is not called pure.
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 NinevehWhoever hates his sins will stop sinning; and whoever confesses them will receive remission. A man can not abandon the habit of sin if he does not first gain enmity toward sin, nor can he receive remission of sin without confession of sin. For the confession of sin is the cause of true humility.
