Perhaps the world’s most well-known hymn has turned 250 years. It was written in 1773 by a former captain of a slave ship.
Even 250 years after its first publication, the song is by far the most popular hymn of all time.
The song was written by the Anglican preacher John Newton, most likely in December 1772. Since then, it has been sung by many.
The hymn speaks about the grace of God, which Newton experienced as a sinner. 
The word amazing means stunning, unbelievable and undeserved grace.
Before he became a pastor, Newton was active as a slave trader who hauled slaves from the west coast of Africa and brought them to America.
Newton was converted in 1748 when he was caught in a violent storm at the age of 22. Newton then prayed to God and promised to sanctify his life.
He then became a pastor in Olney.
