A Light As It Were of Serenity

From The Confessions of Saint Augustine:
Take Up and Read
So was I speaking and weeping in the most bitter contrition of my heart, when, lo! I heard from a neighbouring house a voice, as of boy or girl, I know not, chanting, and oft repeating, “Take up and read; Take up and read. ” Instantly, my countenance altered, I began to think most intently whether children were wont in any kind of play to sing such words: nor could I remember ever to have heard the like.
As With Saint Antony
So checking the torrent of my tears, I arose; interpreting it to be no other than a command from God to open the book, and read the first chapter I should find. For I had heard of Antony, that coming in during the reading of the Gospel, he received the admonition, as if what was being read was spoken to him: Go, sell all that thou hast, and give to the poor, and thou shalt have treasure in heaven, and come and follow me: and by such oracle he was forthwith converted unto Thee.
I Seized, Opened, and in Silence Read
Eagerly then I returned to the place where Alypius was sitting; for there had I laid the volume of the Apostle when I arose thence. I seized, opened, and in silence read that section on which my eyes first fell: Not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying; but put ye on the Lord Jesus Christ, and make not provision for the flesh, in concupiscence.
Instantly
No further would I read; nor needed I: for instantly at the end of this sentence, by a light as it were of serenity infused into my heart, all the darkness of doubt vanished away.
