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

In the same way neither can we, without the assistance of divine grace, undertake actions such as are acceptable to God. Even should we, while in this condition, succeed in doing anything good, it will be of little or no avail towards attaining the bliss of heaven. But to love and serve God as we ought is something too noble and too sublime for us to accomplish by human powers in our present lowly and feeble condition, unless we are assisted by the grace of God.
