Although this hymn is attributed to Joseph Cook (1859-1933), it was published before he was born. It appears in 1843 in the book "First Truths; or Lessons and hymns for Christian children" (London: Society for Promoting Christian Knowledge) and was probably published in an earlier source. Joseph Cook quoted this text in his last speech to Parliament, which is probably where confusion originated.
