Chapter 37 — Part IV: Prayer — The Third Petition: Thy Will Be Done on Earth as It Is in Heaven
Section 30. God requires that in serving Him we be actuated by the greatest love and by the most exalted charity; that although we devote ourselves entirely to Him with the hope of receiving heaven as reward, yet the reason we look forward to that reward should be that the Divine Majesty has commanded us to cherish that hope. Let all our hopes, therefore, be based on the love of God, who promises to reward our love with eternal happiness.
