In 'Biblical Ethics', Chambers says that God's ultimate purpose in Christ's atonement is to readjust humanity to Himself. This calls for a moral response on our part involving thought, feeling, and will that flesh out the ethical principles of the Christian faith. 'Moral Foundations' takes us deep below the surface of everyday life where the foundations for enduring sainthood are laid. Chambers' instruction in righteousness illumines the dim regions of the soul in the blazing light of holy Scripture. Sin always breaks hearts, spoils lives, and crushes human potential. In 'Philosophy of Sin', Chambers helps us to understand what is wrong with humanity and how the basic wrong can be put right through Christ's atonement, which makes possible human repentence and appropriation of faith.
