God created us for a purpose. Each one of us is unique, but each one has a destiny of eternal happiness. We reach this destiny by freely embracing the will of the God who made us, as it is manifested to us in the circumstances of our daily life. This book provides the modern reader with guidance on how to reach intimacy with God and happiness with him forever by bringing one’s life into conformity with his will. The book consults many sources–the Bible, the teachings of the Church, and the lives of the saints–and in all three the formula is the same: Obey God in all things. In discerning the will of God, there are many questions to consider: What is the relationship between human freedom and divine Providence? What good can result from sin and suffering? What is a vocation, and how does a person hear this calling from God? These questions are considered in chapters divided according to the verses of Psalm 119, which praise God’s commands as expressions of his will. All the saints of the Church have this in common: They sought to discover the Creator’s will for them and then tried to accomplish it to the best of their ability and according to the grace they received from God. The task of all of us is to do likewise.
