Our niece, Monique, gave me a present for Christmas, called A Prayer for Every Day, 2017. It includes prayers from every religion, as well as words of wisdom from great men and women across centuries and the world. This is where I found the words from Lincoln that I posted on his birthday last Sunday.
"Lady and Lord, bless my country. Guide its governors, show them the path to take, make their actions conform to the way of nature. Knit together the many peoples into one tribe; unite us, make us a family, as indeed we are under your loving gaze." ~ Prayer for a Nation
The publishers selected this prayer for Washington's Birthday, but didn't say where it originated.
