The Third Step Prayer can be found on page 63 of the Big Book, second paragraph:
God, I offer myself to Thee -
to build with me and do with me as Thou wilt.
Relieve me of the bondage of self,
that I may better do Thy will.
Take away my difficulties,
that victory over them may bear witness to those I would help
of Thy Power, Thy Love, and Thy Way of life.
May I do Thy will always!
