'Redemption' is a Christian book that attempts to explain the concept of Redemption to a general audience. In Christian theology, redemption refers to the deliverance of Christians from sin. It assumes an important position in salvation because the transgressions in question form part of a great system against which human power is helpless. Redemption is seen as a metaphor for what is achieved through the Atonement; therefore, there is a metaphorical sense in which the death of Jesus pays the price of a ransom, releasing Christians from bondage to sin and death.
