I like the title! If your motives is to bring glory to Jesus and to help others, then I pray for your success! As this is a social site and we have not met any of the people, it is difficult to say one thing our another. I have met people like you describe and my heart is always while a person is still alive, that they would come to repentance. It is one thing to have lived through such a hell on earth, but to stay there is another. Like Paul said, “Forgetting that which is behind!” So as we share our testimony the bite is gone and forgiveness is granted. So we don’t relive the horror every time we share our memories. I can see writing the book and helping others. I can see warning people that have a direct contact with said person out of love. I don’t see the benefit in this social environment a face to face confrontation. I live in the Philippines! Also, the Holy Spirit will reveal to me all that is necessary in my relationships. Please don’t bring your battle over to my blog. It actually looks like an effort to sell your book.
I hope you don’t get this wrong, as I am not saying you are telling something that is not true. I am saying, you wrote a book and I pray for your success in helping others. We comfort others with the comfort we received.
God bless!
