Excellent book!
Format: Kindle
Jeremy Treat has given us a practical and understandable view of Jesus’ atonement on the cross. Not only has Christ redeemed us, He has freed us to serve others and live His life in us as we share the message of His sacrifice and atonement in a fallen world. “Behold, I am coming soon!" Revelation 22:12 HIGHLY RECOMMENDED! Blake Boyd Los Angeles CA

Beautiful Book
Format: Kindle
This books was stunning in its depth and simplicity; the multifaceted dimensions of the atoning work of our Triune God are clearly laid out. This is definitely a book I will be reading again and again, and I am thankful for Treat’s God-given ability, as a pastor-theologian, to simply expound and help us meditate on the glories of the cross. If I could meet this guy I would just shake his hand and thank him profusely. Love his work, and through his work have come to love Jesus more.

Attempting to Unravel Complex Ideas
Format: Paperback
Christian theology is interesting in that it is both readily accessible, and multi-layered (and quite complex). As a Christian, I can see the way Christ's teaching was designed to be understandable to all, in all walks of life and all educational backgrounds. That's a big part of why it is so profoundly moving and effective. However, the atonement is a surprisingly deep subject when we as more mature Christians (or at least more educated ones) try to delve into how exactly Christ's sacrifice on the cross worked. I am not an expert by any means, but I found this book deep and enriching in the ideas it presents. I have yet to fully grasp them or figure out how I feel about a few of them. But such is the way of studying the atonement - Christian theologians have been considering it for two millennia. The writing style is accessible enough, I was able to follow it without an issue. I consider this book more of a jumping-off point for further study than a conclusive explanation of all the facets of the atonement as we (try to) understand them.
