Husband After God by Aaron & Jennifer Smith
I have enjoyed this devotion book so much. Personally, I read each devotion with my wife and then we discuss the reading afterwards. They also wrote Wife After God as well.
Radical by David Platt
I think it’s clear in the highlighted passage why I love this book. To quote another Platt fan “I have been raised in church my whole life, but reading this book I feel like I am just now beginning to grasp the basics of Christianity”. I’m currently in chapter five and can’t get enough. I can’t stress enough; buy and read this book.
