This book covers a wide range of doctrines relating to our experience of salvation, starting with our need, moving on to consider what is involved in becoming a Christian, majoring on justification (being put right with God) and also more briefly considering sanctification (living the Christian life). As well as expounding these doctrines the book introduces the reader to the historical roots of these doctrines, to classical expositions of them from the past.

These doctrines are in danger of being lost by significant sectors of Evangelicalism and the aim of the book is to expound them clearly. Tony Lane encourage readers to hold firmly to an Evangelical soteriology, having greater understanding of it and a greater conviction of its truth. Some of the chapters have an immediate application to Christian discipleship.
