I have a theory:
I think that at some point in your life, you were a version of yourself that was the best version that God wants you to be. Be it when you were 12 or 8 or 20. He gave you a taste of what it was like so as life whirled along at a break-neck speed and you journeyed further and further from your best self, you'd remember it, be reminded of it in little ways and journey back to it...........and him.
Then, when you finally pick up that strand in your life's weaving that was the best version of you, it is familiar, good. and you never, ever let it go.
But..............it's just a theory.
