The first book I read that truly helped me become saved was: Addiction Approval By Joyce Meyers
The second book I recommend for helping, guiding, supporting your prayer life is: Praying to change your life by Suzette Caldwell.
And the Third book I just finished reading to support you through a separation in your life, it leads more towards Marraige separation but as you read the book it can relate to any type of separation you have experienced or about to experience in your life, how to cope with it and how to seek God and get closer to him: Waiting and Separated by Jan Northington.
Let me know if you have read any of these books or if you do and what you think or thought about them. God Bless!
