Although the human heart weighs less than a pound, it is the most vital organ of the body. A bone called the sternum guards our heart. Without this bone, our hearts would be vulnerable to puncture and damage. The heart is the wellspring of our physical life. God knew this vital organ needed protection because it provides life-giving blood flow to the rest of the body. It has to be protected and guarded to give life. He uses our hearts as an illustration to our spiritual lives too. If we contaminate the heart with sin, it will feed the rest of the body sin, which will lead to death. In the same way, living in God’s presence is life-giving. This book will share God’s story—His relentless love for you seen in the ultimate sacrifice of his son Jesus and the work of the Holy Spirit in your life.
