The Serenity Prayer is the common name for a prayer written by the American theologian Reinhold Niebuhr^[1][2] (1892–1971). The best-known form is:

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.

The prayer has appeared in many versions. Reinhold Niebuhr's versions of the prayer were always printed as a single prose sentence; printings that set out the prayer as three lines of verse modify the author's original version. The most well-known form is a late version, as it includes a reference to grace not found before 1951.

Serenity Prayer

God, give me grace to accept with serenity
the things that cannot be changed,
Courage to change the things
which should be changed,
and the Wisdom to distinguish
the one from the other.

Living one day at a time,
Enjoying one moment at a time,
Accepting hardship as a pathway to peace,
Taking, as Jesus did,
This 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.

Amen.

Some twelve-step recovery programs use a slightly different version:

God grant me the serenity to accept the things I cannot change,
Courage to change the things I can,
and the Wisdom to know the difference.^[5]
