This book is a 13-lesson workbook for adult classes. Thirteen Bible imperatives that use the words "be" or "be not" are examined. Paul said, "Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect" (Rom 12:2). These 13 lessons have been tested in adult Bible classes of different sizes.
