A changed life

Saint Augustine of Hippo is considered by many to be the father of Western Christianity, although he lived in Africa, born some three centuries after the birth of Christ. But he wasn't raised as a Christian. Here he describes his conversion, which occurred after a time of spiritual turmoil in Augustine's life:

I cast myself down I know not how, under a certain fig-tree, giving full vent to my tears; and the floods of mine eyes gushed out an acceptable sacrifice to Thee. And, not indeed in these words, yet to this purpose, spake I much unto Thee: and Thou, O Lord, how long? how long, Lord, wilt Thou be angry for ever? Remember not our former iniquities, for I felt that I was held by them. I sent up these sorrowful words: How long, how long, "to-morrow, and tomorrow?" Why not now? why not is there this hour an end to my uncleanness?

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. 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. 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. 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.

After his conversion, he wrote this beautiful prayer:

Here is my heart, O God,
here it is with all its secrets.
Look into my thoughts, O my hope,
and take away all my wrong feelings.
Let my eyes be ever on you
and release my feet from the snare.
I ask you to live with me,
to reign in me, to make this heart
of mine a holy temple,
a fit dwelling for your divine majesty. Amen.
