St. Theophan the Recluse: The Lord, having entered into union with the spirit of man...

"The Lord, having entered into union with the spirit of man, does not immediately fill him completely or dwell in him wholly. This is not because of any reluctance on His part - for He is ready to fill everything - but because of us; it is because the passions are still mixed with the powers of our nature, not yet separated from them and not yet replaced by their opposite virtues."
