From the historical Jesus and his disciples through to the present day, Greg Sheridan has written an impassioned, informed and utterly compelling case for the truth and importance of Christianity in our lives.

He presents a strong argument for the historical reliability of the New Testament, meets the living Jesus there, explores the extraordinary personality of Paul, celebrates Mary's activism and examines the magnificent richness of John.

Filled with insights, intelligence, warmth and humour, Greg also introduces us to a range of fascinating Christians today, among them political leaders and young activists offering the radical Christian interpretation of love to their generation.

His book explores the journey of those who have been guided by faith, such as Gemma Sisia, whose school in Tanzania has transformed the lives of thousands of children, and the dynamic Chinese Christians pursuing their beliefs under harsh restrictions.

He examines where Jesus can be found in popular culture and talks to Christian leaders - Pentecostal, Catholic, Evangelical and others - in Australia, the US and Britain.

At a time when the chasm of understanding between secularism and faith has never seemed wider, Christians is timely, relevant and convincing.
