Touching expression Supernatural process for understanding identity & purpose
Format: Kindle
This book provides a very touching and practical expression of the Divine component to understanding our identity and purpose. TD Jakes identifies the posture, process and focus we need to have in order to be ready to receive what God is seeking to impart to us in his Divine the appointed time and way.

Great Read!
Format: Kindle
This is an excellent reminder for most of us who are in transition from one level to the next in their spiritual journey. Jake's asks thought provoking questions at the end of each chapter to not only emphasize a point made in the material presented, but more importantly to give the reader an opportunity to internalize its meaning. I will keep this in my library and suggest it to others who may also be struggling with purpose and identity.

Great book
Format: Kindle
Provides perspective on seeking to fulfill your purpose in life. Identity teaches on really allowing God to bring open doors to you while you remain faithful to what you've already been tasked to do. I recommend this book to anyone seeking out their destiny.
