We all know the Serenity Prayer, right? If you've ever been to an AA or AlAnon meeting, you are introduced to this right off.
God, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference.
No -- not yet, "amen." Reinhold Niebuhr began his prayer with those lines, and here is the rest. Enjoy meditating on this, the unknown portion of this wonderful prayer:
...Living one day at a time,
enjoying one moment at a time;
accepting hardship as a pathway to peace;
taking, as Jesus did,
the sinful world as it is,
not as I would have it;
trusting that You will make all things right
if I surrender to Your will;
so that I may be reasonably happy in this life
and supremely happy with you forever in the next.
