"Amazing Grace" is a Christian hymn with words written by the English poet and clergyman John Newton (1725–1807), published in 1779. With the message that forgiveness and redemption are possible regardless of sins committed and that the soul can be delivered from despair through the mercy of God, "Amazing Grace" is one of the most recognizable songs in the English-speaking world.
Newton wrote the words from personal experience. He grew up without any particular religious conviction, but his life's path was formed by a variety of twists and coincidences that were often put into motion by his recalcitrant insubordination. He was pressed (forced into service involuntarily) into the Royal Navy, and after leaving the service became involved in the Atlantic slave trade. In 1748, a violent storm battered his vessel so severely that he called out to God for mercy, a moment that marked his spiritual conversion. However, he continued his slave trading career until 1754 or 1755, when he ended his seafaring altogether and began studying Christian theology.
