“I once was lost, but now am found,
Was blind, but now I see.”
John Newton, “Amazing Grace”, 1772

John Newton was slave ship master for several years, bringing enslaved Africans to England. In 1754, after becoming violently ill on a sea voyage, Newton abandoned his life as a slave trader, the slave trade, and seafaring, altogether, wholeheartedly devoting his life to God’s service.
In later years, Newton fought alongside William Wilberforce, leader of the parliamentary campaign to abolish the African Slave Trade. He described the horrors of the slave trade in a tract he wrote supporting the campaign and lived to see the British passage of the Slave Trade Act 1807.
