A short thank you note

Dear ______,

I want to write you to say thank you for what you said to me yesterday morning. You most likely had no idea of the impact your comments made, so I think it's fair to let you know that you helped change the course of my day yesterday.
Sometimes the gap between who I am and who I want to be gets bigger than I think I can handle, and the lack of forward motion on my part at times really tempts me to wonder if I'm really meant to be doing what I'm doing. I know that what we're going after as a church demands a certain level of excellence, and my internal response to a lot of what comes my way is often less than stellar, despite my best efforts.
That you were able to notice some measure of worth in my attitude tells me two things I really needed to hear:
1) I'm a little more than useless, and
2) God has to be at work, because no way on my own am I capable of the grace you accused me of showing. :)

So if God is with me (which he always is), then, like Troy says, I have no right to quit. Thanks for reminding me of that.
:)
