Around minute 31:20, he begins to talk about this prayer, and how he says it even though he feels hypocritical doing so. A man after my own heart.
“God, I offer myself to Thee-to build with me and to 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!”
He says he thinks the prayer comes from Saint Francis, but actually its from the “Big Book,” and was probably written by Bill W.
“If you cannot pray sincerely, offer your dry, hypocritical, agnostic prayer;
for God in His mercy accepts bad coin.” — Rumi
