In chapters 3-6, I've most appreciated how McGraw highlights what the day is for. He rightly points out that this was true from the moment the Sabbath was sanctified, not a new teaching in Isaiah 58, since what is necessarily implied is as binding and true as what is implicit.
The chapter on worldliness is especially helpful as it searches out the reason that so many resist even the idea of an Isaiah 58 type Sabbath--and how some who at first attempt to keep it do not find it joyous.
