Blooming where you're planted

How can God use me, a stay-at-home-mom with a limited social circle and interaction with strangers?  In the grocery store, in lines at the pharmacy and over a couple racks of heirloom tomatoes at the local market:
After a conversation of how good that first summer tomato sandwich will taste, how Jackson River Road used to be called Cedar Creek and on why he chooses yellow 'maters over red, and "would you guess that I'll be 80 years old next month?" I asked him bluntly - 'where will you go when you die?'
Yup.  I threw it out there and didn't even flush.  I said it like the "how to witness" books tell you to, how the Sunday School lessons suggest, how I've heard of others doing it.
"In the ground, I guess."
'No, you know what I'm talking about, after y- - - '
"I don't believe in any of that mess.  Now, look, I can go through that Bible and show you where its wrong and there's nothing in it ~ for starters (holding up a bony finger), how can ONE being, ONE thing create all of this (waving his hand over the tomato patch and at the mountain behind us) in six days?  What about the fish in the ocean?  And the universe, too?  There's just no way that ~ why, we've even PROVED it that dinosaurs was here for millions of years and the Bible expects us to believe the earth is only 7,000 years old?  And people coming back from the dead after all that ~ they's just no way they was dead in the first place...now, I was baptized way back in the, the, I was born in '31, ya know; I was baptized and I used to believe all that but then I got to thinkin' how there was just no way the Bible could be true, what they tell you young people, its all wrong...."
"You've obviously given this a lot of thought, but see hear those two kids squallin in the car over there?  They're mine, and I'll have to get them home.  I'd been wondering if I'd be seeing you in eternity."
"There's no such thing.  When I go in the ground I'm staying there.  Now, I can see I"m making you mad with all this, but you just have got to know that you're wrong about all this.  There's no such thing as all that, you'll find that out for yourself one day ~ that Bible is, well, its just all wrong you know..."
"I'm not mad at all, in fact I am feeling pretty good right now, but my girls are getting louder, can't you hear them?"
"I know I made you mad, I make a lotta folks mad about this, but I know I'm right about it, you're mad..."
"No sir, I just have to get my girls home.  I don't get mad!  If anything I feel sorry for you because I know what I believe and I wish you the best yourself, have a nice day!"
"Waaal, I knowed I made you mad..."

I wasn't mad.  I was praying!
