the serenity prayer
"God grant me the serenity" is one of the most popular prayers in the world, and is most well known in its short form (up to and including the line "wisdom to know the difference"). It is thought that the words after this, which form the long version of the serenity prayer, were added at a later date, and are probably the work of a different author. The original words are attributed to the Christian writer and theologian Reinhold Neibuhr (1892-1971).
The Serenity Prayer
God grant me the serenity
To accept the things I cannot change;
Courage to change the things I can;
And wisdom to know the difference.
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;
Taking, as He did, this sinful world
As it is, not as I would have it;
Trusting that He will make all things right
If I surrender to His Will;
So that I may be reasonably happy in this life
And supremely happy with Him
Forever and ever in the next.
