Awesome Awesome Awesome!!
Format: Paperback
You know they say 'what you don't know won't kill you'..... nothing can be further from the truth when it comes to God's love and grace. Arthur and his wife have help remove 'manifold blinders' from my heart's eye about our everlasting loving Father. Definately a keeper. Thanks Arthur and Cathy!!
