In The Grumble-Free Year, the Goyers invite readers into their journey as they go complaint-free and discover what it looks like to develop hearts of gratitude. They share their plans, successes, failures, and all the lessons they learn along the way, offering real-life action steps based in scripture so that readers get not just a front-row seat to the action but also an opportunity to take the challenge themselves and uncover hearts that are truly thankful.
