1. I, Tim, am writing in my own voice because most of this volume is based on a series of nine sermons I preached in the fall of 1991, during the early days of the ministry of Redeemer Presbyterian Church in New York City. Nevertheless, this book is very much the product of two people’s mutual experience, conversation, reflection, formal study, teaching, and counseling over thirty-seven years. Kathy and I have come to our understanding of marriage together. Even those nine sermons were mainly the fruit of our common effort to understand marriage in Christ. I just did the reporting.
