Praise God, then I came across this book that was on my mother's bookshelf, that's when I found greater understanding of Him, all praises to a Holy Father. This book has meant so much to me, that I've even given it as a gift a few times. As Christians, when we come into the Grace of who Holy Spirit is and His purpose in our lives, we are able to flow in the things of our Father with greater ease, wisdom, knowledge and understanding.
So, if you know of someone who is struggling with the 'idea' or the purpose of Holy Spirit and who He is, this book would be a wonderful teacher for that individual. You can read an excerpt of this book here.
