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!
