We 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 AthoniteMore Silouan the Athonite quotes
The Lord greatly loves the repenting sinner and mercifully presses him to His bosom: "Where were you, My child? I was waiting a long time for you." The Lord calles all to Himself with the voice of the Gospel, and his voice is heard in all the world: "Come to me, my sheep. I created you, and I love you. My love for you brought Me to earth, and I suffered all things for the sake of your salvation, and I want you all to know my love, and to say, like the apostles on Tabor: Lord, it is good for us to be with You."
Silouan the Athonite
No matter how much we may study, it is not possible to come to know God unless we live according to His commandments, for God is not know by science, but by the Holy Spirit. Many philosophers and learned men came to the belief that God exists, but they did not know God. It is one thing to belief that God exists and another to know Him. If someone has come to know God by the Holy Spirit, his soul will burn with love for God day and night, and his soul cannot be bound to any earthly thing.
