Roman Catechism 33.11

Chapter 33 — Part IV: Prayer — On Prayer in General

Section 11. Proof — Nor can we, for a moment, doubt that God in His goodness awaits and is at all times ready to hear our petitions -- a truth to which the Sacred Scriptures bear ample testimony. Since, however, the texts are easy of access, we shall content ourselves with citing as an example the words of Isaias: Then shalt thou call, and the Lord will hear: thou shalt cry, and he will say, "Here I am"; and again, It shall come to pass, that before they call, I will hear: as they are yet speaking, I will hear. With regard to instances of persons, who have obtained from God the objects of their prayers, they are almost innumerable, and too well known to require special mention.
