Iohn Containing a very profitable discourse of conscience, and of al the actions, sortes, and kinds thereof, wherby euery man may easily know his estate, wherein hee standeth in the sight of his God, and whether his conscience be good or euill, with all things also belonging either to get a good conscience, or else to releiue it out of trouble, being grieued and wounded, as in the epistle to the reader is more specially mentioned, and in the discourse itselfe clearely expressed.
