There's a new book coming out soon on Francis Schaeffer's apologetics, entitled Truth with Love. You can read the introductory material online for free.
I haven't yet read it, but look forward to doing so. Here are the blurbs:
“Truth with Love powerfully demonstrates that while Schaeffer’s thought stands up to scrutiny, it is his distinctive style that enabled him to herald the Christian message with such compelling power.”
William Edgar, Professor of Apologetics, Westminster Theological Seminary, Philadelphia
“More than a thoughtful assessment of Francis Schaeffer’s apologetics. An encouragement to Christians to love people around them and to bear witness of the truth of the gospel.”
D. A. Carson, Research Professor of New Testament, Trinity Evangelical Divinity School, Deerfield, Illinois
“By skillfully and graciously responding to Schaeffer’s critics, Follis reveals how extraordinarily powerful and relevant Schaeffer’s ideas are.”
Rev. Ranald Macaulay, Coordinator, Christian Heritage, The Round Church, Cambridge
“The best introduction to Schaeffer’s apologetics. Follis captures the unity of commitment to the Christian message and a life that lives that message faithfully—a unity that characterized the ministry of Francis Schaeffer.”
Jerram Barrs, Resident Scholar of the Francis Schaeffer Institute at Covenant Theological Seminary
“The real Francis Schaeffer—Reformed apologist, youth evangelist, lover of God and of people—is here profiled and celebrated. The best appreciation of Schaeffer and his legacy yet written.”
J. I. Packer, Professor of Theology, Regent College; author, Knowing God
