I've just finished this amazing theological-fiction-peace-giving book. Now, don't misunderstand, it's not all 'happy, happy, we're so happy now' but rather an amazing look at what God the Father, Son and Holy Spirit might be like were we to spend a weekend with Them, and working through some issues to bring healing to the soul.
I found Mack's journey quite eye-opening and hope that many will be inspired by it. But I do caution --- it is fiction (as far as we know). :) There are many beautiful phrases that capture your heart as you read it, but were they to be quoted out of context or with the intent of being a new look at God and a new revelation of Him, it might cause some conflict with Scripture. And no one would want that to happen! Discussion points - sure! Bring them on! Dreaming of time without end in the presence of God and our loved ones - priceless!
I thoroughly enjoyed the book and highly recommend it.
