Who was David in the Bible? Agents of Grace examines David— one of the most revered people in the Old Testament— and how God worked in his life. Author Robert Koester shows that David certainly had his share of human flaws. However, God used his agents— the people around David— to influence David and lead him back to the righteous path. God does the same for us in our present-day world. He puts other people in our lives to guide and shape us— whether it' s a family member, friend, coworker, or a stranger on the street— people all around us can be God' s agents of grace. In this book, you' ll learn about King David and the people who shaped his life, and you' ll begin to see how God uses the people in your life to shape you as well.
