The Canterbury Press Lent book for 2021 focuses on the significance of the story at the very centre of Christianity: the crucifixion. Samuel Wells writes as a theologian and pastor to explore the cross in the purposes of God and how this act brings about salvation.

Three sections, each with six short chapters, explore the cross in:
- the Old Testament (Covenant, Test, Passover, Atonement, Servant, Sacrifice)
- the Epistles (Forgiveness, Obedience, Foolishness, Example, Reconciliation, Boast)
- the Gospels (Finished, Judged, Betrayed, Pierced, Forsaken, Mocked)

Written with characteristic clarity and wearing its considerable learning lightly, A Cross at the Heart of God will give readers a comprehensive understanding of the story at the heart of scripture, the central event in history and a core tenet of the Christian faith.

A study guide with questions and prayers makes this ideal for Lent groups as well as individual reading.
