The Hound of Heaven

According to Wikipedia: "The Hound of Heaven is a 182 line religious poem written by English poet Francis Thompson. The poem became famous and was the source of much of Thompson's posthumous reputation. It was included in the Oxford Book of English Mystical Verse (1917). It was also an influence on J. R. R. Tolkien, who read it a few years before that.... Francis Thompson (16 December 1859 13 November 1907) was an English poet and ascetic. After attending college, he moved to London to become a writer, but in menial work, became addicted to opium, and was a street vagrant for years. A married couple read his poetry and rescued him, publishing his first book, Poems in 1893. Francis Thompson lived as an unbalanced invalid in Wales and at Storrington, but wrote three books of poetry, with other works and essays, before dying of tuberculosis in 1907."
