St. Theophan the Recluse: The root of good inner order is the fear of God...

The root of good inner order is the fear of God. 

Preserve this fear within you constantly: it will hold everything taut, and will allow no slackness either in physical members or thoughts, creating a vigilant heart and a sober mind, and allowing no bodily torpor or blurring of thought.

"But one must always remember that success is any aspect of the spiritual life is the fruit of the grace of God. Spiritual life comes entirely from His most Holy Spirit. We have our own spirit but it is void of power. It begins to gain strength only when the grace of God flows into it."

St. Theophan the Recluse
