The following anecdote comes from the Memoir of Eustace Carey. On a certain occasion, a lady said to William Carey, “Mr. Carey, I see adult baptism to be quite right, and yet I cannot make up my mind to submit to it. I am very unhappy about it sometimes; I suppose you would advise me still to pray about it, sir?” Said Mr. Carey, “I tell you what I advise, madam; go and do what you know to be right, and pray afterwards. Your prayers will then be likely to give you more pleasure.”
