I'd prefer to keep this simple and short.
WHY, oh why, do I strive for a thing which cannot be gotten by way of desire, hope, daydreaming or tears?
THING. Meaning: a confidant stance before the living God.
That thing, that promise, is a gift given to those who believe. If I believe it, that gift allows me to stand blameless and perfect before Him, to find my purpose in Him, and to find my end in Him.
And on that weighty thought, I'll end this post and go to bed.
