Carey explores how Tillich's ideas of "Kairos" (the opportune moment) and "Logos" (divine reason) intertwine to shape his theological perspectives. The book delves into Tillich's influences, including existentialism and Christian theology, and discusses how his thoughts address the human condition, faith, and the nature of God.
