When the soul knows the love of God by the Holy Spirit, then he clearly feels that the Lord is our own Father, the closest, dearest Father, the best. And there is no greater happiness than to love God with all the mind and heart, and our neighbour as ourself. And when this love is in the soul, then all things bring joy to the soul. ~ St. 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 known 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 believe 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. ~ St. Silouan the Athonite
Understand 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. ~ St. Silouan the Athonite
