It is told of Sadhu Sundar Singh that many years ago he was distributing Gospels in the Central Provinces of India and he came to some non-Christians on the railway train and offered a man a copy of John's Gospel.
The man took it, tore it in pieces in anger and threw the pieces out of the window. That seemed the end, but it so happened, in the Providence of God, there was a man anxiously seeking for truth, walking along the line that very day and he picked up as he walked along a little bit of paper and looked at it and the words on it in his own language were 'the Bread of Life'.
He did not know what it meant; but he enquired among his friends and one of them said: 'I can tell you; it is out of the Christian book. You must not read it or you will be defiled.' The man thought for a moment and then said: 'I want to read the book that contains that beautiful phrase': and he bought a copy of the New Testament.
He was shown where the sentence occurred-our Lord's words 'I am the Bread of Life'; and as he studied the gospel, the light flooded into his heart, he came to the knowledge of Jesus Christ, and he became a preacher of the gospel in the Central Provinces of India.
That little bit of paper through God's Spirit was indeed the ‘Bread of life’ to him, satisfying his deepest need. - John A. Patten.
John 6:35 (ESV): Jesus said to them, "I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst.”
