And let no one think himself too wise for such child’s play. Christ, to train men, had to become man himself. If we wish to train children, we must become children with them. Would to God such child’s play were widely practiced. In a short time we would have a wealth of Christian people whose souls would be so enriched in Scripture and in the knowledge of God that of their own accord they would add more pockets, just as the Loci Communes, and comprehend all Scripture in them. Otherwise, people can go to church daily and come away the same as they went. For they think they need only listen at the time, without any thought of learning or remembering anything. Many a man listens to sermons for three or four years and does not retain enough to give a single answer concerning his faith–as I experience daily. Enough has been written in books, yes; but it has not been driven home to the hearts. (Luther’s Works, v. 53, p.64-67).
