Yes, you should read this book!
Format: Kindle, Format: Kindle
This book is a fantastic read. It's as if you're having a casual conversation with Tim Ross about faith and it goes by so quickly. This book is for you if you're struggling to understand to have a healthy relationship with God, found yourself in a rut of just doing religious practices, if you're struggling with fully submitting to God, or if you're unsure of if you're being impactful when you witness to others. I'd say you can even read this book as if it's a devotional because there are great reflection questions and notes at the end of each chapter. Slow down, really take in the words, pray, and reflect to get the most of out of this book!

Get yourself to the Basement!

This book is for this season for sure. It was so personable, practical, and profound. I felt as though we were having a conversation with Tim and considered myself a virtual podcast audience member reading it. Transforming and upsetting your life starts first internally and Tim shows us how. I feel so encouraged and ready to take the leap into upsetting the world around me. Get yourself to the basement !

Get to the safest place in a building- The Basement
Format: Hardcover, Format: Hardcover
This book is a simple and poignant call to arms- or should I say, call to open our arms- for ALL followers of Christ. Take Tim Ross' hand and let him lead you through the acceptance and vulnerability of what it means to be a disciple. It shines the light on the reality of our brokenness and gives us real life examples of how to flip things on their heads to bring our pieces to the only one who can truly mend us.
