Roman Catechism 37.22

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

Section 22. We are not easily induced to entreat God not to satisfy our inordinate desires. This disposition of soul is difficult of attainment, and by offering such a prayer we seem in some sort to hate ourselves. To those who are slaves to the flesh such conduct appears folly; but be it ours cheerfully to incur the imputation of folly for the sake of Christ who has said: If any man will come after me, let him deny himself. This is especially so since we know that it is much better to desire what is right and just, than to obtain what is opposed to reason and religion and to the laws of God. Unquestionably the condition of the man who attains the gratification of his rash and inordinate desires is less enviable than that of him who does not obtain the object of his pious prayers.
