The Heidelberg Catechism: Lord’s Day 49
124. Question: What is the third petition?
Answer: Thy will be done, on earth as it is in heaven. That is: Grant that we and all men may deny our own will, and without any murmuring obey Thy will, for it alone is good. Grant also that everyone may carry out the duties of his office and calling as willingly and faithfully as the angels in heaven.
