Simply put: I just read the most theologically challenging book: Men and Women in the Church by author Dr. Sarah Sumner. By far, the most important book I've read in a long time (except the Bible, to me there is absolutely nothing better than God's Word ever).
I read this as a textbook. It wasn't a walk in the park mentally. I wrestled through it and with it. I was faced with questions I wasn't ready for, and some of them quiet honestly I was scared of the answers. I was given a mirror at times and saw within my heart some deep prejudices that I did not even know I had. At many points throughout the text I was deeply convicted.
So let me warn you: do not attempt to read this book unless you are spiritually ready. Do not dive into the text without prayer. Do not attempt to go it alone either – there are discussion questions at the end of each chapter – read it with someone.
