When I first became a Christian, about fourteen years ago, I thought that I could do it on my own, by retiring to me rooms and reading theology, and I wouldn’t go to the churches and Gospel Halls;… I disliked very much their hymns, which I considered to be fifth-rate poems set to sixth-rate music. I came up against different people of quite different outlooks and different education, and then gradually my conceit just began peeling off. I realized that the hymns (which were just sixth-rate music) were, nevertheless, being sung with devotion and benefit by an old saint in elastic-side boots in the opposite pew, and then you realize that you aren’t fit to clean those boots. It gets you out of your solitary conceit.
