Understand two thoughts, and fear them. ( 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
