"The Christian Church has always been a missions community. If God is to stir the slumbering embers of Christian hearts in the West our passion for missions must be rekindled. Norman Mackay's straightforward, easy to read, and quite convincing work might well be used to awaken many to the real issues."
John Armstrong, Director of Renew and formerly a Pastor for twenty years
"We have here a clear biblical apologetic for the words of Jesus ‘No-one comes to the Father except through me.' ... a necessary analysis and a timely warning to today's world. It needs to be digested and applied."
Colin Peckham, 1936–2009 – Former Principal of Faith Mission College, Edinburgh
"Global Warning is welcome for its author's unequivocal commitment to biblical truth, and evident passion for the task of world evangelisation."
John Brand, Principal, Faith Mission Bible College, Edinburgh
"Mission is the raison-d'etre of the Christian Church. Yet Christians can easily find a thousand different reasons for avoiding it. This book is an uncompromising critique of such evasiveness and should disturb every evangelical conscience. It should also fire us all to go and tell every man and woman, 'I have good news for you.'"
Donald Macleod, Retired Principal of Free Church College, Edinburgh, Scotland
"With good research and careful reasoning Mackay calls for us to wake up to the insidious influences of pluralism and relativism."
Rev. David Ellis, OMF International
... excellent and timely book, well written, well argued, and well illustrated. Readers will find it encouraging, sobering, instructive and challenging.
"Global Warning is a soul-stirring wake up call for Christians living in a self-absorbed age. It will rekindle your heart with a passion for world evangelisation."
John MacArthur, Chancellor Emeritus, The Master’s University and Seminary and Pastor–Teacher, Grace Community Church, Sun Valley, California
"This unique cutting-edge missions book will not be easy for some of us to digest, but the message is greatly needed at this moment in history."
