O God and Heavenly Father,
Grant to us the serenity of mind to accept that which cannot be changed;
the courage to change that which can be changed,
and the wisdom to know the one from the other,
through Jesus Christ our Lord, Amen.
Serenity Prayer--Reinhold Niebuhr
主啊，天上的父親，
求你賜我們安祥去接受不能改變的事實，
賜勇氣去改變能夠改變的事物，
以及賜智慧去區別這兩者，
奉耶穌的名 ，阿們。
