St. Alphonsus Liguori
“Oh, how sweet a joy it is, to remain with faith and tender devotion before an altar, and converse familiarly with Jesus Christ, who is there for the express purpose of listening to and graciously hearing those who pray to Him; to ask His pardon for the displeasures which we have caused Him; to represent our wants to Him, as a friend does to a friend in whom he places all his confidence; to ask Him for His graces, for His love, and for His kingdom; but above all, oh, what a heaven is it there to remain making acts of love towards that Lord who is on the very altar praying to the Eternal Father for us, and is there burning with love for us; since indeed that love it is which detains Him there, thus hidden and unknown, and when He is even despised by ungrateful souls! But why should we say more? ‘Taste and see.'”
