When we first published this book in 1996, there was some debate over its title: in the end we settled for Open the Door because that is what we wanted people to do. However something needs to happen before we open the door: we need to get ready. 1 Peter 3:15 shows we are always to be ready and this book will help us do just that. "But sanctify Christ in your hearts, always being ready to make a defence to every one who asks you to give an account for the hope that is in you, yet with gentleness and reverence." Reachout Trust is an international Christian ministry with 25 years experience of equipping the church to do just that. Its primary aim is to uphold Biblical truth and reach out to people who have been caught up in the cults, occult and new age. Doug Harris is the founder director of the Trust. He travels extensively conducting seminars, TV and radio interviews and is the author of several books.
