Tony Lane surveys a wide range of doctrines relating to our experience of God's gracious salvation.

He begins with our need as sinful and fallen people, moves on to consider what is involved in becoming a Christian - majoring on justification (being put right with God) – and concludes with sanctification (living the Christian life). As well as expounding various aspects of these doctrines, Lane introduces their historical roots in classical expositions.

Lane warns that these doctrines are in danger of being lost by significant sectors of evangelicalism, and he explains them clearly. He encourages readers to hold firmly to an evangelical soteriology, having a greater understanding of it and a stronger conviction of its truth, with experience of its application to Christian discipleship.
