Man does not live on bread alone

If you are a Christian, you may have heard the song "Amazing Grace." But have you ever thought of the man behind the song? It's John Henry Newton, a British sailor who was involved in the slave-trade in the 18th century and later embraced the Faith firmly.
I will not give so much details about his life because you can easily search it in the Internet. I just want to point out that his story is a proof of our search for something more sublime than our worldly existence.
It proves the truism of the Bible's assertion that man does not live on bread alone.
The story goes that John Newton, described as a man without any "religious conviction" before his firm embrace of the Faith, had a spiritual conversion after a storm almost sank his ship, the Greyhound.
It was said that at the height of the storm he muttered "God, have mercy upon us". Reflecting on what he had uttered when he returned to his cabin he came to believe that God was addressing him through the storm and thereafter slowly moved towards the Faith.
That led him to compose the song "Amazing Grace" with its haunting melody and lyrics "I once was lost but now am found". In his lifetime as lay minister in the Anglican Church he has composed dozens of religious songs.
That also led to his involvement in the campaign against slavery, his former trade, in the 18th century when merchant ships took foodstuffs and goods to Africa and then returned with slaves to be sold to Europe.
John Newton did not invoke God's name out of the blue. In his childhood, he was nurtured by his mother, Elizabeth, in the Faith but the virtues of Christianity did not sink into his heart and followed the lure of the sea in the footsteps of his father.
John Newton was among many people who found life's "light" in the Faith. There was C.S. Lewis, a former atheist, who later wrote religious books, the most famous of which is "Mere Christianity". The latest of note I know is Charles Colson, special counsel for former president Richard Nixon and the first to be jailed among the seven indicted in the Watergate scandal.
He was already toying with the idea of embracing the Faith after seeing the emptiness of politics before his indictment and pleaded guilty to the charges of cover-up in keeping the new-found faith.

I am fascinated with their stories because I myself was a former atheist who embraced the Faith after a long life storm.

Here's the appropriate gospel on the subject:

Scripture says; one does not live on bread alone, but on every word that comes from the mouth of God. - Matthew 4:4
