You have a minister, and your minister is called a divine because by courtesy he is supposed to understand that divine work, and to be engaged on it night and day in himself, and in season and out of season among his people.

He will tell you how you are to make you a new heart.

Or, if he does not and cannot do that; if he preaches about everything but that to a people who will listen to anything but that, then your soul is not in his hands but in your own.

You may not be able to choose your minister, but you can choose what books you are to buy, or borrow, and read.

And if there is not a minister within a hundred miles of you who knows his right hand from his left, then there are surely some booksellers who will advise you about the classical books of the soul till you can order them for yourselves.
