Just read Sway: The Irresistible Pull of Irrational Behavior and it is an absolutely fascinating read. Like the kind of book you can’t wait to read the next page to see what it says.
It’s about why people make bad decisions. What are the things that pull people towards making decisions that aren’t in their best interest?
It’s a business book, not written for pastors, but it is chock full of applications for the church.
