The Scotch people are especially fond of this hymn. The author prefaced it with these lines: ”Since I first discovered Jesus to be the end of the law for righteousness to every one that believeth, I have more than once met with a poor sinner seeking peace at the foot of Sinai instead of Calvary, and I have heard him again and again in bitter disappointment and fear groaning out, 'What must I do?' I have said to him, 'Do, do? What can you do? What do you need to do?"'
