In this book Macquarrie addresses questions that often stand in the way of faith in God and Christ. He explains Christian faith and doctrine in an historical context and in light of a growing secular sense that God has become unnecessary. Macquarrie shows how faith in God and Christ answers life's deepest questions while accommodating the doubts of reasonable persons and the dislocations of society.
John Macquarrie FBA TD was a Scottish-born theologian and philosopher. Timothy Bradshaw has described Macquarrie as "unquestionably Anglicanism's most distinguished systematic theologian in the second half of the twentieth century."
