Wow, what a wordy sentence! I’m not even going to attempt to edit it. It is the best I can do to explain about prayer, because, in my heart, I know that prayer is unexplainable. My heart also lets me know when prayer is making a difference. My heart, touched by grace, tells me that I have to pray, and so I do.
Theophan the Recluse (1815-94), saint in the Russian Orthodox Church expresses it this way.
“—the turning from the outside world to one’s inner self, and the subsequent turning from self toward God." Theophan the Recluse say we can do this 'when we are quickened by grace,' but WE HAVE TO DO IT.
