It’s a little beyond Thanksgiving, the holiday, but I watched Dr. Jeremiah on a Christian TV channel and liked the subject—thankfulness. Thought it would be good to have it on file. http://www.lightsource.com/ministry/turning-point/video-player/thankful-for-what-435307.html The sermon begins at about 19:50—or you can watch and listen to the music (contemporary) and then sermon. Take away. Thankfulness is not a feeling, it’s an action. The feeling will come after the action.
Paul is the “thankfulness” writer of the Bible, and most of those letters were written from prison.
