Basic, Profound, and Thorough
Format: Paperback
I'm a deliverance minister and walk people through forgiveness exercises on a regular basis because of the spiritual freedom that comes with forgiveness. This book is basic but very thorough and covers all the high-level points on the importance of forgiveness without getting into the weeds. Book is thin; not overwhelming to non-readers.

Excellent book!
This is the best book on forgiveness that I’ve ever read. Only read this if you are serious about working through unforgiveness and bitterness. I learned that it is okay to have boundaries and limitations, but first you must forgive.

Buy more than one! Shareable!
Format: Paperback
This is a small book and a quick read, but don’t let that fool you. It’s packed with truths that will encourage the reader to forgive those that have wronged them. This book was required reading for a class I took. After reading it, I decided to buy several copies to give to friends.
What you’ll learn: When someone offends us we often feel we have a right to an apology, and perhaps we do. We might even want revenge. But what we don’t realize is that unforgiveness only hurts the one offended. It’s like filling a cup with poison for your offender and then drinking it yourself. You become poisoned by your own hurt, anger, thoughts or words against that person. When we refuse to forgive, we become enslaved to bitterness, and bitterness can take root in our mind, spirit, and body. We become sick.
When we forgive, we release the offender from blame, or forgive their debt to us. We leave the situation (or revenge) in God’s hands, and we move on. The result is freedom!
“For if you forgive other people when they sin against you, your Heavenly Father will also forgive you.” Matthew 6:14
