"What an awesome book! It was a blessing to me—offering a rare, Scripture-based framework for stewarding capital with excellence and real-world impact in places like Africa, where 80% of the world’s poor are."

—Henry Kaestner, co-founder of Faith Driven Investor and Faith Driven Entrepreneur
"Inspiring, intellectually rigorous, and deeply practical, this is an essential guide for Christians who want to ensure their compassion translates into the greatest possible impact for the world’s most vulnerable people. It’s a beautiful, moving book."

—Will MacAskill, co-founder of 80,000 Hours and Giving What We Can and author of Doing Good Better
"I couldn’t put this book down. It manages to be both inspiring and practical. It blends cutting-edge research with careful theological discussion... it is essential reading for Christians who are trying to figure out how to steward their resources wisely."

— Lara Buchak, Professor of Philosophy at Princeton University
"All The Lives You Can Change... should be mandatory reading for Christian clergy and for every Christian who wants to live their faith to the fullest."

— Bruce Friedrich, co-founder and president of The Good Food Institute
