Grace and Glory:
The more I live, the more I discover that I am a mystery to myself.
Yes. This is quite true for all of us. No one can possibly know himself as thoroughly as God knows him, on any level–physical, psychological, spiritual.
Do you know the configuration of every atom comprising your body; have you counted the hairs on your head? Do you know unfailingly all your motivations, desires, weaknesses, strengths? God does.
Ontologically speaking, God has to be intimately connected to each of us, because he created us from nothing, and continually holds us in being.
To paraphrase Frank Sheed, if you make something, then walk away from it, what keeps it in existence is the material that you made it of–wood, metal, clay. But God made us (and the universe) out of nothing. If he walks away, what continues to hold us in existence? Nothing.
Thomas Merton once said that at the center of being of each of us, whether great sinner or great saint, there is God, holding us in existence.
(And that of course, is entirely apart from a consideration of
Grace–the indwelling of the very life of God.)
