This hymn was written in 1758, and it was the first hymn in a collection of hymns for the user of the Church of Christ. Nettleton is the name of the tune composed for this hymn, by John Wyeth. Fred Bock was an organist in California who played and arranged both piano and organ music. In one of his books he tells that he enjoyed playing the piano more than the organ. That's where I am too. Someone asked me about that, saying that organists have to use their feet a lot, like their whole body. But I said, "Yes, but when you press an organ key, either hard or soft, it comes out the same, depending on the pipes you chose, but on the piano you can play each key 20 different ways, and I enjoy working at that. Plus you still use your feet.
