Isaac Watts, composer of this hymn, was a tutor for a wealthy family in London when he felt the call to enter the ministry. In 1699 he became assistant pastor of a small, dying church. Soon the congregation swelled and they built a much larger house of worship called Mark Lane Church of London. In 1707 Isaac Watts sold the copyright to this hymn and it has been sung in churches worldwide for over 300 years.
Final line of the hymn: Love so amazing, so divine, demands my soul, my life, my all.
When I Survey the Wondrous Cross.
