John Bunyan's reaction to praise of his sermon

After reading Craig's blog post, There are no great sermons, I remembered that John Bunyan, author of Pilgrim's Progress, and a valued preacher, had something to say on the subject. The following extract is from Life of Bunyan by Rev. James Hamilton:

But popular as he was, he was not fond of praise. One day after he had concluded an impressive discourse, his friends pressed round to thank him for his "sweet sermon." "Aye," he bluntly answered, "you need not remind me of that; for the devil told me as much before I left the pulpit."
