A two-volume study in the strategy of Christian evangelism as developed by two of its greatest exponents, set in the framework of biographical studies. Volume I covers the life and thought of Blaise Pascal, while Volume II covers the life and thought of Sen Kierkegaard, each volume standing in their own right as scholarly contributions to the literature of their respective subjects.

Although far separated in time and tradition, Pascal and Kierkegaard both insisted that self-complacent humanity needs first to be disturbed, and then comforted, by the Gospel.

Most of the book is occupied by a thorough review of the lives and works of the two men, in such a way as to ring out their significant place in the spiritual history of modern Europe. But the author's purpose throughout is not merely biographical. He goes on to compare the conception and execution of their evangelistic tasks in a way which brings out the remarkable consensus between them; and in an epilogue he draws conclusions relating this historical study to the tasks and methods of modern evangelism.
