Using New Testament passages, Thomas examines how the Christian is to think, and explains how a correct, biblical view of self should radically transform our Christian living.

Starting from the premise that 'how we think has everything to do with how we behave' (p. 14), he emphasises our need to understand the 'death/life' paradox in order to be able to live lives appropriate to our new identity in Christ. Thomas goes on to examine various aspects of the Christian life including: our relationship to the Law; family tensions and responsibilities; the enticements of the world; suffering for our faith; witnessing to others; fruitfulness and its implications; Christian submission; following the will of God; and biblical definitions of success and failure.
