I am thankful for answered prayers!
I know that can be a long topic ... but I guess I mean that I am thankful for
prayers that are answered in the way I expect - for instance,
praying you'll find something you've misplaced, then finding it!
(which is exactly what happened to me - I needed to locate an important document and couldn't remember where it might be since the move and everything!!)
and, especially, I am thankful for those prayers that are answered before you
"officially" pray for them ... God knows!!!
