From the Life and Teachings of Elder Siluan by Bishop Alexander and Natalia Bufius translated by Anatoly Shmelev

The soul that is in all things devoted to the will of God rests quiet in Him, for she knows of experience and from the Holy Scriptures that the Lord loves us much and watches over our souls, quickening all things by His grace in peace and love. Nothing troubles the man who is given over to the will of God, be it illness, poverty or persecution. He knows that the Lord in His mercy is solicitous for us. The Holy Spirit, whom the soul knows, is witness therefore. But the proud and the self-willed do not want to surrender to God's will because they like their own way, and that is harmful for the soul.
