by St. Ambrose of Optina
One ascetic woman was besieged for a long time with unclean thoughts. When the Lord came and cast them away from her, she called to Him: ‘Where were you before now, O my sweet Jesus?’ The Lord answered: ‘I was in your heart.’ She said then: ‘How could that be? For my heart was full of unclean thoughts.’ The Lord said to her: ‘Know that I was in your heart, for you were not disposed to the unclean thoughts, but strove rather to be free of them; and when you were not able to be free, you struggled and grieved. By this you prepared a place for Me in your heart.’
