Saint Augustine spent much of his life searching for truth and happiness until he discovered God. He realized that only by living with God could humans truly be happy. The document outlines Jesus' teachings on happiness from the Sermon on the Mount, known as the Beatitudes. The Beatitudes describe the qualities of those who will be happy, such as being poor in spirit, meek, and merciful. They show how to live like Jesus by embracing difficulties for the sake of righteousness.
