Since God has given us his Son, whom he loved as himself, how can we fear that he will deny us any other good that we ask of him? If, therefore, he has given us his Son, he will not refuse us pardon for the offences which we have committed against him, provided we detest them; he will not refuse us the grace to resist temptations, if we implore it of him; he will not refuse us his holy love, if we desire it; he will not, finally, refuse us Paradise, if we do not render ourselves unworthy of it by falling into sin. Behold how Jesus himself assures us of this: If you ask the Father anything in My name, He will give it you.
--St. Alphonsus Liguori, The Incarnation, Birth and Infancy of Jesus Christ
