Our spiritual heart guides our actions and behavior. It speaks of our integrity or deceit, love or anger, obedience or rebellion. While sin has caused our imperfections, we all have the core ingredients for faith and obedience to have a relationship with God. The Heart of the Bible walks the reader through the Old Testament to demonstrate how relationships with God either flourished or withered away based on acting--or not acting--on those core ingredients. What do the actions of Cain and Abel, Ruth, Saul and David, and others teach us about the nature of the heart? What were the consequences of a contemptuous heart? What were the warnings from the prophets and their messages of hope in God's path for salvation? How will the heart be renewed in God's plan? Answers to these questions and more are provided in this compelling read for lay people to grasp and apply these lessons.
