By obedience a man is guarded against pride. Prayer is given for the sake of obedience. The grace of the Holy Spirit is also given for obedience. This is why obedience is higher than prayer and fasting.
Silouan the AthoniteWhoever will not love his enemies cannot know the Lord and the sweetness of the Holy Spirit. The Holy Spirit teaches us to love our enemies in such way that we pity their souls as if they were our own children.
Silouan the AthoniteWe suffer because we have no humility and we do not love our brother. From love of our brother comes the love of God. People do not learn humility, and because of their pride cannot receive the grace of the Holy Spirit, and therefor the whole world suffers.
Silouan the AthoniteUnderstand two thoughts, and fear them. One says, "You are a saint," the other, "You won't be saved." Both of these thoughts are from the enemy, and there is no truth in them. But think this way: I am a great sinner, but the Lord is merciful. He loves people very much, and He will forgive my sins.
