I just finished the short book, Where’s God?, by Frank Viola. Viola compiles the responses from more than 20 well-known Christian ministers and thought leaders on the topic of suffering and unanswered prayers.
I may not agree with all of them, but I did gain some insights. I always think it is beneficial to the larger body of Christ when we get to hear from diverse voices, so I greatly appreciate works like this one.
The main reason I am promoting this book is that they have made it available for FREE to anyone. You can get your copy here: https://www.frankviola.org/whereisgod/
