William Cowper was an English poet whose reflective and emotionally rich writing influenced both literature and hymnody. His personal struggles and deep introspection shaped the tone of his devotional works, which often explored themes of divine providence and human frailty.

His hymns include There Is a Fountain Filled with Blood and God Moves in a Mysterious Way. These hymns are known for their poetic depth and theological insight.

Cowper collaborated with John Newton on the Olney Hymns, contributing many texts that became enduring pieces of English hymnody.
