Chapter 37 — Part IV: Prayer — The Third Petition: Thy Will Be Done on Earth as It Is in Heaven

Section 17. We Ask That We May Fulfil What God Desires Of Us — When, therefore, we pray, Thy will be done, we first of all ask our heavenly Father to give us the strength to obey His Commandments, and to serve Him in holiness and justice all our days; to do all things according to His will and pleasure; to discharge all the duties prescribed for us in Sacred Scripture; under His guidance and assistance to perform all that becomes those who are born, not of the will of the flesh but of God, thus following the example of Christ the Lord who was made obedient unto death, even unto the death of the cross; finally, to be ready to bear all things rather than depart from His holy will in even the slightest degree.
